MKS Precisive

Precisive’s online and real-time infrared gas analysers use an innovative all-optical technology with the sensitivity and specificity comparable with Gas Chromatographs but without the need for analyser calibration, these highly advanced analysers are as effective, more efficient and less costly than traditional GC-based monitoring systems.

Tried and tested in some of the harshest field environments, MKS – Precisive aims to develop real-world solutions for the environment you work in. This technology has resulted in astounding benefits. With an extremely robust design at less than half the cost of traditional Gas Chromatographs and no need for analyser calibration, these systems offer incredible value for money with very low maintenance required.

MKS – Precisive’s incredible technology is more efficient than Gas Chromatographs with real-time response, multi-compound detection and high sensitivity.

Australian Dynamic Technologies are Australian distributers for MKS – Precisive on-line and real-time infrared gas analysers. Using an innovative all-optical technology with “GC like” sensitivity and specificity, these products have built in, permanent analyser span calibration. These highly advanced infrared gas analysers are as effective, more efficient and less costly than traditional GC-based monitoring systems.

In a number of applications, it can be important to perform analysis of C1 to C5 alkane gases which include propane, butanes, methane, ethane and pentanes, for exmaple BTU measurement and analysis of biogas and natural products. Residual oxygen (or Calorimeter as it is well known) approaches have been costly and required substantial servicing and maintenance. The Gas Chromatography technique has provided the ability to separate compounds with a high degree of selectivity.
