Product Detail
The new EGM II is the only gas introduction module to use semi-automatic injection sequencing that allows you to generate a calibration curve using just one calibration gas. This innovative solution means that your laboratory no longer has to handle and purchase numerous gas bottles, and you also reduce total analysis times.
Principle of operation The EGM II is a semi-automatic sample introduction accessory for gas and liquefied gas. The 10-fold rotary valve holds two sample loops; one for gas and one for liquefied gas. The volumes of the sample loops are user definable, but 10 mL and 100 µL (respectively) come as standard. In loading position the sample gas flows through the sample loop to the vent. The loading sequence is controlled by the EGM II; initiated either by pressing the purge button or as a part of the injecting sequence. Depending on the mode (set by the gas/liquids-switch) the corresponding venting valve is opened and the sample gas flows through the sample loop.
After loading the sample loop, the EGM II is ready to inject the sample into the analyzer. By turning the rotary valve (automatically) the carrier gas forces the sample out of the loop towards the heater and expansion vessel. This way the gas is stabilized for pressure and temperature and if the sample is a liquefied gas it is vaporized at the same time. From the expansion vessel the sample gas is fed into the analyzer to be analyzed on Total Sulfur, Total Nitrogen or Total Chlorine.
