Repeatability is insured by accurate temperature and pressure control, by constant incubation time and by use of the Valve & Loop technique. This allows a known, repeatable amount of the gas phase to be introduced, regardless to system pressure and without using a syringe, thus avoiding the risk of condensation.

HSS 86.50 is easy to use and can be coupled to GC or any other gas chromatograph or GC/MS.

HSS 86.50 is able to analyse up to 44 samples in 20 or 10 ml vials and to optimise analysis times for high productivity: one sample is heated while the previous sample is analysed. This process eliminating waiting times

between each run.

The following features make HSS 86.50 more flexible and extend its range of applications:

- Constant Heating Time: used for consistent sampling, this features allow to analyse samples under the exact same time and temperature conditions;

- MHE technique (Multiple Headspace Extraction): used for quantitative analysis of complex matrices, particularly solid samples.

- Automatic increase of incubation time and temperature: both parameters, essential for determining the sensitivity of a method, are gradually increased by a constant value. Optimum conditions can be readily identified from chromatographic responses;

- Sample shaking: a mechanical system without the use of magnets, allows shaking at two selectable power settings. The shaking of the sample during heating reduces incubation times and improves sensitivity and repeatability;

- Variable loops: from 0.5 to 3 ml, offer maximum application flexibility and compatibility with any capillary or packed column.

The chemical inertness of the sample pathway, the low dead volumes and the constant washing flow to negligible levels improve sensitivity and maintain the peaks shape unchanged and the sample integrity.
