    MULTIDETEK3 User’s manual 5. Specifications 5.1. Detector cautions The MultiDetek3 uses multiple detection techniques known from the industry for many years. It can be PED, FID, TCD and other types on request. The principle of the PED is based on spectroscopic emission. The detector is a pure quartz cell put in an electromagnetic field created by a specific high-intensity generator.

    MULTIDETEK3 User’s manual 5.3. Start-up All LDetek products are properly packed in a cardboard box and all instruments come with an associate document name “Operating parameter”. Refer to the steps below to ensure the proper start-up for this unit. 1. Unpack the instrument carefully from the box and inspect it to be sure it is in good condition and hasn’t been damaged during shipping.

  • Page 17: Figure 3: Oven Setpoint

    Settings>>Oven select the right oven and look at the first value of the timetable (beside “at start”). If after few minutes, the oven temperature deviation is still active and no temperature change occurred, then it is required to contact LDetek support for further instructions.

  • Page 18: Figure 4: Flow Setpoint

    The detector will turn on automatically once the carrier gas set points and a basic purge of the system are achieved. If after confirming the above you still have an active ‘Detector # OFF’’ alerts displayed, then it is required to contact LDetek support for further instructions.

  • Page 19: Figure 5: Operating Parameters

    Due to the vibrations during shipping, sometimes the system properties are modified and could result changing in the elution time of peaks. In this case, LDetek experts will be able to guide you in the modification of the system parameters with the file provided.

  • Page 20: Shut-Off

    MULTIDETEK3 User’s manual When all peaks appear at the right timing using the span gas, the span calibration o f the system can be done. Refer to section 7.4 of this manual for calibration menu details. After running the span calibration, the system can be switched on process gas and is ready for normal operation.

Valves actuation Separating the actuation from the reference carrier gas allows our gas chromatograph MultiDetek3 to achieve better results and more stability. The reason for it is mainly caused by the pressure changes when valves actuate during a cycle that will impact the equilibrium of the carrier gas reference.

  • Page 28: Hardware Description

    6. Hardware description The MultiDetek3 has major components included in its chassis. This section will describe each component that can be replaced for maintenance or upgrade. 6.1. Detectors The PED detector module is a 155 mm (6.1”) x 82 mm (3.22”) x 63 mm (2.48”) box that contains all components needed to proceed to accurate measurement.

  • Page 29: Motherboard

    6.2. Motherboard This I/O board controls all components inside the analyzer (flow, detectors acquisition, temperatures, etc.). When replacing this motherboard be sure to avoid any electrostatic contact. The Board conception is modular, so it facilitates the replacement of parts on site. The flow sensor for carrier and sample can easily be replaced on site.

  • Page 30: Sample Gas Proportional Valve, Mini Pump, Or Septum Injector

    For some applications with condensable gases, the valves can be mounted in a heated box contained by the MultiDetek3 chassis. That heated box can also be purged with inert gas when hazardous or toxic gases are present. Please contact LDetek for more information.

  • Page 31: Carrier Gas Electronic Pressure Regulator (Ldepc)

    Carrier gas electronic pressure regulator (LDepc) The carrier gas flow control in the MultiDetek3 is managed by a high purity LDetek electronic pressure controller (EPC). The carrier flow control can be mounted inline or in bypass mode depending on the application.
