It looks like the connector will have to be changed to a standard one. The power supply for the device must be 15V 5A and have a sufficiently specific connector.Swagelock gas and sample connectors look good, well threads.

However, only authorized personnel can replace these filters, therefore it is to your advantage to install the optional external sample filter kit (KIT-2052) to protect the internal filters whenever you suspect that particulate matter may be present. These filters protect the fine passages inside the instrument. The sample inlet contains a 10u filter and the injector contains two built-in 5u filters.

The M200/ M200H contains several internal filters.

Okay, only 1/8-inch clean metal tubing can be used for gas supply. Do not use any kind of plastic tubing for the carrier gas since air will diffuse through the tubing which may cause noisy baselines and decreased sensitivity. The M200 should be connected to the carrier gas tank with 1/8-inch stainless steel, copper or aluminum tubing.

The M200/ M200H uses a 1/8-inch Swagelok fitting on the back panel for carrier input.

Almost everything that I have seen (for welding and other needs) has a rather low accuracy of maintaining pressure and they are all "one-stage regulators". It turned out that a fairly accurate pressure regulator is needed. A two stage pressure regulator is recommended to lower the tank pressure for the M200/ M200H to 80 psig ☒ psig (see Figure 7).

A carrier gas is typically supplied in a tank at pressure up to 3000 psig.

The manual indicates a fairly serious number for the level of gas purity. Impurities in the gas can create false peaks. When analyzing low ppm of oxygen and nitrogen, the helium should be at least 99.99995% pure. Choose a gas with a purity of at least 99.9995%.

The carrier gas should be dry and of high purity.

Different gases have different cooling capacities. The carrier gas must be exactly the one indicated on the device.

Use of another carrier gas generates filament temperatures that are too high and that result in damage to the detector if run at the standard voltage levels.

Your M200/ M200H is configured at the factory to use helium/ hydrogen or nitrogen/ argon as the carrier gas.

This means that the pneumatic system must be fully connected to power up.

This gas cools the wires and keeps their temperature in the operating range. Carrier gas or carrier gas with the test substance from the separation column always passes through the wires. The higher a detector sensitivity - the higher the filament current, the more wires are heated. The «resistances» of the detector are thin wires to which the filament current is applied. The bridge also has a balance control, and an autozero circuit to zero the detector output between runs.The user can select high, medium or low sensitivity levels which changes the gain level of the electronics. Therefore, the resistance of the analytical side changes and the output indicates a peak is eluting.Ī regulated power supply controls the voltage being fed to the filaments at a constant level. When a component elutes, the thermal conductivity on the sample side of the bridge changes. When both sides have pure carrier gas flowing over the filaments, the bridge is balanced and the output is zeroed. The bridge compares their resistance against those of the reference side (R1). In an TCD, pure carrier gas elutes from the analytical column and passes over two matched filaments (S1).
