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...
Golden Rules of Micro GC: Carrier Gas Quality
When installing a new device, we draw attention to the tips for using your Micro GC Fusion. This modular technology is very robust. A device can perform millions of measurements without requiring any...
H2S: If You Can Smell It, That's Actually a Good Sign!
Why is H2S surveillance important? The H2S, also known as hydrogen sulphide, is a dangerous gas, easily recognizable by its rotten egg smell. Very flammable and toxic, it forms when organic matter decomposes without oxygen,...
Understanding Backflush: Why Use It and How It Works?
Backflush is a must in gas analysis! Find out what it's for and how it works. In gas chromatography, there are different analytical columns allowing the separation of different species. We choose its column(s) in...
Methane: it's not just the cow's fault!
Methane is often associated with a herd of cows in a meadow. But while the agricultural sector is indeed a major emitter, it is the only reason why this gas is crucial. At CHEMLYS, we accompany you in...
Ammonia analysis: a key tool in many areas
A compound with several uses... Little known to the general public, ammonia, also called « NH3 » is an indispensable tool in many areas, including industry and agriculture. It is a chemical compound essential for the production of fertilizer, number of...
GC-VUV Applications: #1 Fuel Analysis
Fuel analysis is complex and subject to many standards. Depending on the needs, many analytical methods exist (GC-FID, GC valves, etc.) and sometimes coexist, making processing of the results complex and time-consuming....
Interest of Silconert treatment in sampling reactive products (sulphur, NOx, Mercury...)

Stability and performance: Micro GC Fusion® innovation
All analytical equipment requires maintenance phases. These can be punctual (replacement of wear parts) or recurrent (calibration, drift correction, etc.). These recurring maintenance phases must be the least frequent and the most frequent...
Simplify natural gas analysis with Micro GC Fusion®
Natural gas is part of our daily life, whether it is to cook, heat or even move.In order to guarantee its performance, it is important to know its composition and thus deduce its calorific value (PCI and PCS). As part of the...
Applications of Micro GC Fusion #2
Presentation of one of our customers in the field of renewable energies: HAFFNER ENERGY – the production of green hydrogen by pyrogasification. If hydrogen as such does not pollute, getting hydrogen is not simple because it is not readily available in the natural state.
