    Mass Spectrometer Theory The mass spectrometer allows you to identify the masses of individual atoms and molecules that have been converted to ions from a given sample. This technique is unique in that it provides a fingerprint identification for the structural and chemical properties of these molecules.

  • Page 14 Separation Once the ions reach the quadrupole mass filter, they are filtered according to their mass-to-charge (m/z) ratio. Each ion has an identifiable mass. The quadrupole mass filter is constructed of four electrically-conducting, parallel cylindrical rods. A constant direct current (DC) voltage and an alternating radio-frequency (RF) voltage is applied along the length of the rods.

This current is then sent to the preamplifier for ampli- fication and then to the data system for display. When an electron multiplier is used, the ions are attracted to the multiplier be- cause of its negative charge.

  • Page 43: Chapter 4 Communications Protocol

    COMMUNICATIONS PROTOCOL Host Communications The Dymaxion has two serial ports, an RS-232 and an RS-485. A switch on the Dymaxion’s back panel selects the port to use (Figure  4-1). The RS-485 port allows up to 31 power supplies to be connected in a multi-drop-network configuration to one host.
  • Page 44 ??. Use a command with the node set ?? as a network broadcast ad- dress. All Dymaxions will execute the embedded command. To avoid bus contention, no acknowledgment response will be issued. The checksum is a modulo 256 summation of the characters making up the function code and data. For example, to turn on the filament on the Dymaxion at address 01: >0104195[CR] 95h = 30h + 34h + 31h When sending a command, if the inter-character delay exceeds two seconds, the Dymaxion will time-out. The command will be discarded and the Dymaxion will start waiting for the next command.

  • Page 54: Operation

    Operation In order to send commands to the Dymaxion, the host must log in by sending the 00L function. The Dymaxion is organized into 32 data channels. Each of the channels can be set to either tabular (a single mass) or to analog, bar, total pressure, analog input, digital input, or disabled. A “scan” consists of acquiring data for all active chan- nels. The date and time are stored with each scan. All parameters are retained when the Dymaxion is turned off. The time and date are not updated while the power is off. 4-12 | Dycor Dymaxion Mass Spectrometer...

  • Page 55: Chapter 5 Sampling Systems

    SAMPLING SYSTEMS There are a variety of ways to introduce gas samples to the mass spectrometer. The sampling system serves as a bridge between the sample environment and the vacuum environment of 10 to 10 Torr required by the mass spectrometer. If a sample is at the same operating pressure as the mass spectrometer, the sample can be analyzed directly.

    Pumping Systems Pressure/vacuum levels required by the mass spectrometer are achieved by using a pumping system when the sample chamber is operating above 10-4 Torr (Figure 5-7). These pumping systems are application-dependent. Each system has a 70 l/sec (liter/second) turbomolecular pump that is connected directly to the inlet manifold.

  • Page 73: Electron Multiplier / V-Stack Detector

    Electron Multiplier / V-Stack Detector The multiplier is immune to up-to-air cycling and routine low-level ion bombard- ment. However, over time the system will begin to lose gain. When this becomes unacceptable, a new multiplier will restore the original gain of the system. Call AMETEK Process Instruments or your local representative to arrange for factory service to replace the multiplier. Because of the complexity of the detector flange assembly, we recommend that the multiplier be replaced at the factory.
