Safe and reliable gas injection at low concentrations in accordance to ASTM methods

Oct 27 2020 Read 233 Times

Fast and reliable measurement of various parameters in gases and LPG (liquified petroleum gases) is becoming increasingly important. To give a few examples, water in LPG can cause valve and pipe freezing and already low ppm ranges of fluorine and chlorine in LPG can cause corrosion. Also sulphur and nitrogen in feedstocks need to be observed to maintain catalyst performance and for environmental reasons.

Nittoseiko Analytech, formerly Mitsubishi Chemical Analytech, provides gas injectors (GI) and vaporisers for gases (VG) that help to manage these challenges, guaranteeing safety and measuring reliability. Their VG-200, a standalone LPG sample injector for titration systems, can dose a preset volume or mass of LPG into any titration cell automatically. Combined with Nittoseiko Analytech’s CA-310 Karl Fischer titrator it is compliant to ASTM D7995.

For elemental analysis, the GI-220 is specialised to dose ambient or low pressure gases up to 1000 mL injection volume. It is possible to reach LOD down to 5 ppb sulphur, in accordance to ASTM D6667 and D7551.

Nittoseiko Analytech’s GI-260 features fully automatic sampling and injecting out of liquid phase LPG. Multi-loop injection enables calibration from one standard. This instrument is compliant with ASTM D7994 and UOP 1001, when operated with Nittoseiko Analytech’s AQF-2100H combustion ion chromatograph.
