Installation 6.2.1 Hydrogen Supply Installation An 1/8” outside diameter stainless steel capillary tube with two “Swagelok” type 1/8” fittings and flat seals is delivered with the generator. An existing H gas source may be used, such • a supply panel, • a H gas cylinder, or, • a hydrogen gas generator able to deliver 500 ml/min gas at 10 bar. Step1: Connect the capillary SS tube to the gas source 1. Determine the length of the tube needed to reach the source from the generator and add 1m more to form a free loop that can be left behind the generator. The loop will make it possible to move the generator slightly without having to remove the capillary tube. Cut the tube with a saw and deburr the tube ends. 2. Connect the capillary tube to the H gas source with a Swagelok fitting. 3. Attach the tube to the wall. Step2: Connect the capillary tube to the generator Figure 6.1: H Gas Inlet Port 1.
Installation 6.2.2 Exhaust Line Connection In normal operating mode, small amounts of hydrogen can be released through the vacuum pump or through the safety valves and will be routed to the hydrogen vent outlet at the rear side of the instrument. Figure 6.2: H2 Gas Vent Outlet Ten meters of 8 mm flexible plastic tubing are delivered with the generator. The tubing must be connected to the hydrogen gas vent port on the rear side (labeled H ...
Installation 6.2.3 Ethernet Connection The BPHG 90 can optionally be connected via an Ethernet link to an external computer. Connect the Ethernet cable on the rear panel (labeled ETH) to a free Ethernet port on the external computer, using a standard RJ45 Ethernet cable. 6.2.4 USB Connection The generator has an USB port on rear panel for updating the firmware. This port is reserved for use by trained service personnel only. 6.2.5 Mains Power Connection The BPHG 90 is connected to the mains using a 3wire grounded power cord rated for 600 W. ...
Operation Operation The BPHG 90 has been designed to operate in a largely automatic manner. The user has access to different modes of operation via a touch panel at the front of the instrument. The touch panel presents the user with information on operational parameters via a number of screens. A typical screen layout will present a title bar at the top of the screen, possibly some operational parameters in the main field and some buttons for control over the operation (see the next figure). Most operating screens feature a Settings button at the lower ...
Operation Getting Started 1. Open the H gas supply valve and ensure that the hydrogen inlet pressure is in the correct range: 6 to 10 bar. 2. Switch on the generator using the mains power switch on the front panel (see the next figure). Next to the power on switch on the front panel of the BPHG 90 are two LEDs that provide basic status information.
Operation 7.1.1 System Check Window When the BPHG 90 is switched on, the instrument briefly shows a welcome screen and then performs a preoperation System Check of the main components. At the end of the system check, the system displays the System Check window. If any of the tests does not pass, the failed test result is highlighted in (see the figure below) and operation of the instrument is not possible until the user has taken remedial action. Figure 7.4: System Check with Low Coolant Level Warning A special case is the test for the hydrogen sensor that measures the H concentration in air inside the instrument. This sensor needs about a minute to warmup and this is indicated by a message in (see the figure below). When all tests pass, the System Check window disappears after a few seconds and the system enters Standby mode (see section Stand‐by Mode [} 43]). Figure 7.5: Hydrogen Gas Sensor Warming Up 7.1.2 Standby Mode Once the instrument has successfully passed the initial automatic system check, it goes into STANDBY mode. First, a confirmation screen is displayed (see the next figure), asking the user to verify that the exhaust hydrogen gas tube is safely routed outside the room or to a fume cupboard.
Operation The BPHG 90 is delivered with 10 meter of flexible exhaust plastic tubing, which is connected to the rear of the instrument and routed, for example to a fume cupboard or outside the room (see section Exhaust Line Connection [} 38]). Figure 7.6: Exhaust Gas Warning Message WARNING Hydrogen is a very flammable gas. The exhaust hydrogen gas must be safely routed outside the room using the tubing supplied.
The BPHG 90 operations are controlled by a number of parameters which are factory preset. These parameters are accessible via the Settings function (see the next figure) which can be called up by tapping the Settings button at the bottom right hand corner of most operating screens. The main Settings access window has two tabs: • User settings. • Service settings. The Service (BRUKER) is intended only for trained service personnel and is password protected. Figure 7.8: System Settings and User Settings Interface The user has access to two settings screens: General or PHG. The General button offers general system setup functions for e.g. touch screen calibration and system date and time settings.
Operation 7.2.1 Adjustable Parameters In the PHG > Settings window, the user has access to the following operational parameters: • Conversion temperature setpoint (36...40K), default 36 K. • Batch delivery target pressure (0...6 bar), default 3 bar. • Filling container delivery timeout (0... 60 min), default 60 min. Figure 7.9: User Settings Menu with Adjustable Parameters In order to change a parameter value, tap the parameter field. This will bring up a numerical keypad to enter the new value. The user accessible parameters have a limited value range and entering values outside this range will cause the nearest valid value to be loaded. The parameter values are stored in a nonvolatile memory and user defined values...
Operation At startup, when the operating time of any of the maintenance critical components is within 90% of the preset service interval, then a maintenance warning is given, but the system can continue to operate. In this case, the operating information screen will display a warning triangle next to the component indicating it is near its service interval maintenance. ...
Operation Purge Function Before the BPHG 90 can be cooled down for the first time, the instrument must ensure that no gases other than H will be present in any internal tubing and in the conversion chamber. This is to avoid a blockage caused by the freezing of other gases such as CO etc. For this purpose the working volume is first evacuated and then filled with H gas. 2, The process is executed twice and takes a few minutes. The user can select this purge procedure by tapping the Purge button on the Standby screen (see figure Stand‐by Screen with Warm‐up Conversion Chamber [} 44]).
Operation 7.4.1 Cooldown When the cryostat vacuum is good (below 5 mbar), the cryocooler is automatically started. When the cryocooler is functioning, it emits an audible noise, this noise is normal. The sound level of the BPHG generator is below 70 dB at 1 m. While the BPHG 90 is cooling down, relevant parameters are displayed on the cooldown screen. Figure 7.14: Cool Down Screen The cooldown process can be interrupted using the Abort button. When this button is pressed, the user is asked to confirm his action before the cooldown is aborted. The system then returns to the Standby screen.
Figure 7.15: Ready Screen with Access to Main Operating Functions In Continuous Flow mode, the instrument will continuously deliver parahydrogen to the outlet. It is therefore essential that the outlet is connected to a consumption device, such as the Bruker parahydrogen polarizer, and that any waste gas from this device is routed safely out of the laboratory, e.g. through a fume cupboard. WARNING The BPHG90 has NO means of verifying that the delivered gas is handled in a safe manner.
Operation Based on the conversion temperature, the estimated pH yield is indicated as a percentage. 7.5.2 Batch Delivery Mode In batch delivery mode, the BPHG 90 assumes that an EMPTY container is connected to the pH gas outlet on the front panel of the instrument. Ensure that the container used is parahydrogen compatible, i.e. does not contain materials that can quench the hydrogen polarization (e.g. paramagnetic materials). Aluminium bottles are recommended (a suitable aluminium bottle is an optional accessory for the BPHG 90, see section Scope of Supply 29]). When the user presses the button Batch Delivery, the BPHG 90 displays a dialogue screen (see figure Container Connection Dialogue Window) asking for confirmation that an empty container has been connected to the pH outlet of the front panel.
Operation WARNING The generator has no means of detecting the nature of the residual gas is in the container. 1. It is the responsibility of the user to ensure only to connect containers that have been used exclusively for hydrogen. 2. Connecting containers with residual gases other than hydrogen can lead to contamination and blockage of the BPHG 90. The batch delivery continues until a predefined pressure has been reached or until aborted by the user. The delivery process also stops when the preset timeout has elapsed. Progress is indicated in the Batch Delivery screen (see the figure Batch delivery progress screen [} 51]).
Operation Figure 7.20: End of Batch Delivery Process Generator Shutdown The BPHG 90 can be left in Ready mode without detrimental effects to the instrument. If, however, it is envisaged that no parahydrogen is required for a prolonged period of time, it is recommended that the system be switched off. It is not recommended, however, that the BPHG 90 is switched off by means of the main power switch when the conversion chamber is cold. This could lead to pressure build up in the conversion chamber and (a small amount of) H ...
Operation Figure 7.21: Warmup Dialogue and Information Screen The warmup procedure stops when the preset warmup temperature has been reached. Progress is indicated in the Warming up screen and the process can be aborted by tapping the Abort button (see Warm up progress screen with abort function [} 53]). Once the warmup preset temperature has been reached, the system returns to the Standby screen. Then the generator can be safely turned off.
