MultiDetek3 has a rugged 6U rackmount casing and is suitable for both the laboratory and for industrial installation. Typical applications include confirming UHP and specialty gas quality in semiconductor and electronics manufacture, as well as in ASU production facilities. In the energy sector, MultiDetek3 is suitable for monitoring hydrogen and SF6 purity. Other uses include UHP CO2 analysis for food production and winery gas analysis. 

It can be configured with FID/PED or TCD detectors for online trace impurity measurements. The GC is temperature controlled to provide extra stability. The two sample inlets allow it to analyze two gas streams in parallel, providing the same functionality as two separate GCs. 

The PED sensor detects permanent and noble gases, sulfurs, ammonia, hydrocarbons, aldehydes, btex compounds and alcohols among others down to 100 ppt. The FID (flame ionisation detector) is used to detect trace hydrocarbons, with an LDL of 1 ppb, while the TCD (thermal conductivity detector) is designed to analyze higher gas concentrations down to 1 ppm of the target gas.

In addition, users have the option to include dedicated sensors for trace oxygen and trace moisture. For oxygen, the options are either electrochemical or zirconia sensors, and for moisture there is the choice of quartz crystal microbalance or ceramic metal oxide moisture sensors. 

The MultiDetek3 has a large, full-color, touchscreen interface for easy operation. Full reporting is available using LDetek’s LDChroma+ software.
