HSS 86.50 ... reduces sample preparation and assures great
precision
DANI
HSS 86.50 static head space 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 analyze 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 head space 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
head space 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.
