Magnetic susceptibilities and partial pres- sures of gases vary with temperature. In the Model 755R,
1.Interior of the analyzer is maintained at 140°F (60°C) by an electrically controlled heater and associated fan.
2.Immediately downstream from the inlet port, prior to entry into the de-
tector, the sample is preheated by passage through a coil maintained at approximately the same temperature as the detector (See Figure
3.The detector is maintained at a con- trolled temperature of 150°F (66°C).
Also, avoid excessive vibration. To minimize vibration effects, the detec- tor/magnet assembly is contained in a
WARNING
POSSIBLE EXPLOSION HAZARD
This analyzer is of a type capable of analysis of sample gases which may be flam- mable. If used for analysis of such gases, internal leakage of sample could result in an explosion causing death, personal in- jury, or property damage. Do not use this analyzer on flammable samples. Use explosion
Use reasonable precautions to avoid excessive vibration. In making electrical connections, do not allow any cable to touch the
