The sophisticated features of the new DANI HSS 86.50 Head Space Sampler take excellent advantage of the head space technique in any field of application.

The DANI HSS 86.50 uses the Valve & Loop sampling method first developed by DANI and highly prized by operators. Valve & Loop method allows a known and reproducible quantity of gas to be injected independently of system back pressure. Relative standard deviation is usually below 1% and continuous flow of the sample circuit means negligible contamination of memory effect.

DANI HSS 86.50 is a total independent system yet it can be used with any type of gas chromatograph. Interfacing is fast and easy: all you do is connect the carrier gas and insert the transfer line end into the gas chromatograph injection port.

In the last six years, DANI has delivered more than 4000 head space autosamplers, making it the world market leader.

DANI HSS 86.50 ... reduces sample preparation and assures great precision

DANI HSS 86.50 static headspace sampler is the result of 30 years of experience in the production of automatic samplers offering most accuracy, reliability, outstanding repeatability and increase in the productivity of analysis activities.

It allows volatile compounds to be extracted from a non-volatile matrix and to be quickly introduced into a gas chromatograph with reduced sample preparation. Whatever the sample type, the process no longer requires difficult extraction, purification and preconcentration which often cause errors.

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

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

HSS 86.50, used with the DANI PTV injector, is the ideal solution to obtain maximum sensitivity and best analytical performances with highly volatile compounds at low concentrations.

The headspace sampling technique is a tested method used in the most different fields of application.

DANI HSS 86.50 allows analysis times to be reduced and increases productivity while maintaining high standards of precision in a wide range of applications like quality control of food, drinks and industrial products e.g. for the determination of monomer residues in polymers or residual solvents in food packaging.

DANI HSS 86.50 headspace sampler has proved to be particularly useful for monitoring environmental pollution and to determine organic solvents and light hydrocarbons in waters and soils.

Repeatability is assured 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.

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.
