The number of gas fittings as well as their assignment vary depending on analyzer model and

selected options.

All gas fittings are labeled and are normally located at the analyzers rear panel, in case of MLT

2 and CAT 100 they are located at the bottom side.

When it is necessary to open gas paths seal the analyzer‘s gas fittings by using PVC caps to avoid

pollution of the internal gas path by moisture, dust, etc.

The analyzer should be mounted near the sample source to minimize sample transport time. A

sample pump may be used to descrease response time, whereat the analyzer is either operated

in bypass mode or protected by an overpressure valve against too high flow and pressure (see

fig. 5-2).
