Miniature Sampler 2, 10 and 20 ml sample volume!
The GC Vial Liquid Sampler from Mechatest is simply the smallest and best solution to take samples specific for laboratory and chromatography applications.
Direct from the process line, direct into the sample vial!
This unique sampler have a reputation for reliable service and provides accurate samples of many chemical samples, solvent mixtures (particularly aqueous mixtures), but also gasoline is typical the type of sample for which this sampler is ideal. It is this type of multicomponent mixtures for a successful sampling and analysis.
Unique GC vial liquid sampler is ideal for petrochemical and lubricant markets. Good quality and representative samples are vital for any analysis and getting an “unchanged” sample from the process steam to the laboratory is paramount. Within the petroleum related markets samples are typically extracted from process streams in volumes of 50 ml to a litre which is in many cases acceptable when, for example, crude oil and fuel samples are needed. However, in petrochemical and lubricant process streams extracting this volume of sample at multiple stages of the manufacturing process can be extremely wasteful, unnecessary and therefore expensive, with a high cost product every drop counts!
The GC vial liquid sampler from Mechatest has unique needle-in-needle design, it uses extraction needles of 0.6 or 1.2mm diameter and enables direct vial sampling of volumes of either 2, 10 or 20 ml. These are the smallest vial sizes typically found in GC autosamplers and is therefore arguably the best solution for taking samples, specifically for laboratory and chromatography analysis, from a petrochemical or lubricant process stream. Direct vial sampling prevents sample transfer into different bottles, no contamination gives better analysis results!
Direct sampling in small vials prevent broken needles and improve sample transfer and analysis for liquid chromatography applications. It is easier for operation and laboratory people, there is no waste, you spent sample and it is better for the environment.
The GC Vial Liquid Sampler is a typical manual sampler and works with a needle in needle assembly that ensures septum integrity and full venting of process vapors. This unique needle design punctures the septum without cutting it, allowing for full resealing of the septum when the sample vial is removed and is preventing accidental spillage or needle breakage. The vial sleeve is designed for small sample vials with crimp/snap top septum and assures proper alignment and safety for operation. The ability to connect the sampler close to the sample point ensures optimal retrieval of a representative and contamination free sample. In spite of the low dead volume design we recommend to use the sampler in combination with a three-way valve which provides bypass configuration and allows representative product to flow true the valve and after switching directly into the sampler. The pressure drop of the flowing fluid through the sampler process needle is high, the sampler is for low pressure application else you need additional equipment to relief or reduce the pressure. Combination 3-way and 2-way ball valve gives low dead volume and possibility for bypass (circulation) sample flow The special designed needle-in-neelde allow for these small vials complete resealing of the septum when the bottle is withdrawn from the sampler.
