Portable Nitrogen Analyser Model PNITRO
Our latest innovation is a portable ultra lightweight GC, weighing 4 kgs for Nitrogen purity estimation with built-in gas sampling valve to estimate Nitrogen impurity right at the source of Nitrogen supply. It has become a US Pharmacopeial requirement to estimate the purity of Nitrogen, which is used as a carrier gas in Gas Chromatography. When sampling the gas, it is important that the sample collection is done without any environmental contact or exposure so as to ensure that the real impurity profile is captured. Gas transportation with gas sampling bomb, gas sampling bag, such as Tedler bags, are prone to cross contamination. Regular Gas Chromatographs are quite bulky to be taken close the cylinder bank and it is impractical for the cylinders themselves to be carried into the laboratory.
Gases can be directly sent to the GC without any cross contamination without a syringe injection. The Thermal Conductivity Detector (TCD) built into the GC will determine up to few PPM of Oxygen in Nitrogen Gas, thereby providing accurate and reliable results. An easy carry compact carrier gas cylinder of 500 mL volume and a mini laptop will ensure the ease of analyses. The GC works on DC 12V car battery or AC 230 V.
This portable GC is mainly used in Pharma to test the purity of Nitrogen at the source bank.
On-Line gas sampling at the Nitrogen source without the use gas sampling bombs
Measuring range of 1 PPM Oxygen in Nitrogen
Built in TCD (Thermal Conductivity Detector) and amplifier
Total weight of 5 kgs
