Safety and handling of pressurized gas cylinders: good laboratory practice
Safety, double-stage pressure regulator connection, line purging and sealing control: discover the expert step by step guide Chemlys to connect your vector gas to your analyzer (e.g. MicroGC Fusion) without risking contamination of your analyses.
Prevent costly downtime and column damage by mastering routine membrane filter replacement.
Since the micro GC is dedicated exclusively to gas analysis, the presence of liquids or particles can cause severe damage to the apparatus. The most common protective device for micro GC is the membrane filter. This by-pass filter has a very low volume...
Carrier Gas Regulator Connection and Purging: The Complete Technical Guide
The connection and purging of a double-stage pressure regulator connects a cylinder of high pressure vector gas (up to 200 bar) to a gas analyser (GC or microGC). Correctly done, this operation removes air and moisture from the line, in order to...
