Solvent Free
Head Space
The analysis of a gas that is in contact with a liquid or solid sample
The Dynamic Headspace
Technique allows volatile and semi-volatile analytes from the gaseous phase above a liquid or solid sample to be enriched on an adsorbent.
The static headspace technique, the sample is located in a sealed vessel, together with a gaseous phase.
Solid Phase Micro Extraction SPME
The microextraction technique using the MultiPurposeSampler MPS.
All steps are performed automatically and are prepped ahead by the MAESTRO software in a time-efficient way.
The SPME option impresses due to its low phase volume and short extraction times.
Thin Film-SPME
A micro extraction technique that can be partially automated using the MultiPurposeSampler MPS.
It excels thanks to its special phase geometry.
The large volume and large surface area of the adsorbent phase also offer a high degree of sensitivity, even in the case of short extraction times.
The back extraction of the analytes is also possible.
Twister SBSE
The Stir Bar Sorptive Extraction
Enables analytes from liquid or gaseous samples to be enriched solvent-free.
Due to the large phase volume, the Twister is very sensitive and is therefore especially suitable when performing trace analytics.
You can simply use the Twister and reuse it many times. The back extraction of the analytes is also possible.
Direct Thermal Extraction (DTE)
Direct thermal extraction (DTE) is a thermal desorption technique in which a small amount of sample, typically 10-50 mg, is placed in an empty fritted thermal desorption tube or into a small vial (μ-vial) within an empty thermal desorption tube.
The sample is then heated in a thermal desorption unit under a flow of inert gas, in order to release volatile and semi-volatile compounds.
The analytes are trapped and fi nally determined by GC/MS. DTE requires little sample preparation and can be used for trace analysis of volatile and semivolatile organic compounds in solid or liquid samples.
Pyrolysis
Pyrolysis gas chromatography GC is chemical analysis method in which the sample is heated until it decomposes, thereby generating smaller molecules. The temperature used during pyrolysis can be as high as 1000 °C
Examples of the products that are characterized include polymeric materials
OlfactoryDetectionPort (ODP)
ODP 4 is a GC-O-Port that allows the instrumental and olfactory detection of odor-active substances to be performed in parallel.
The substances are transferred without discrimination for sniffing.
During sniffing, you can record olfactory impressions and intensities in order to match them later. Substances of olfactory interest can be isolated and enriched using the function Sniff-and-Trap.
