Derivatisation method development kit
For improved volatility, better thermal stability or low limit of detection in gas chromatography prerequisite: quantitative, rapid and reproducible formation of only on derivative halogen atoms introduced by derivatisation (e.g. trifluoroacetates) allow specific detection (ECD) with the advantage of high sensitivity elution order and fragmentation patterns in MS can be influenced by a specific derivatisation.Reagents for silylation - alkylation (methylation) - acylation are available.Which type of derivatisation is best suited for your sample (alkylation, silylation or acylation)? Test kit for determination of the optimum derivatisation.

Gas filters
Gas filters are an essential part of GC analysis as contaminants in gases can significantly impact the quality of results. Oxygen, hydrocarbons and moisture can lead to problems such as noisy baselines, moisture entering the GC column and excessive bleed. The gas filter kit consists of a gas filter and a connection unit.Fast stabilization timesThe gas filter system consists of two key parts: the filters and the connecting unitThe connecting unit has inlet and outlet connectors for the gas linesThe connecting unit can be bench or wall-mountedCan be used in combination with other filtersIndicator color change tells you when to change your filter
