Hg/hydride systems
Two Hg/hydride systems are available for determining mercury and hydride-forming
metals:
¡ HS Pro PQ – for targeted determination of Hg/hydrides with highest detection
strength
¡ HS PQ – for simultaneous determination of Hg/hydrides with the classic elements
Sampler
¡ Teledyne Cetac ASX-560 sampler
¡ Cetac Oils 7400 sampler
The Teledyne Cetac ASX-560 sampler is suitable for aqueous solutions and has an inte-
grated purging function. It can be equipped with different sample racks and an extra
rack for standard solutions.
The Cetac Oils 7400 sampler allows automatic supply of oils and coolants. It includes a
stirring function and a double purging station for operation with various sample types.
The sampler also has a drip catcher to prevent cross-contamination.
Both samplers can be coupled with the Cetac ASXPress Plus switching valve.
Dilution system
¡ Teledyne Cetac SDX(HPLD) dilution system
The dilution system can dilute samples up to 1:5000. The integrated vortex mixer mixes
the samples with the diluent. The dilution system can dilute responsively and intelli-
gently. The dilution system is controlled via the ASpect PQ
software. The operator can
set parameters such as the maximum dilution factor or the vortex speed easily in the
software.
The dilution system is coupled with the Teledyne Cetac ASX-560 sampler.
Accessories for quick sample
supply
¡ Cetac ASXPress Plus aqueous accessory
¡ Cetac ASXPress Plus oil accessory
Both accessories for aqueous samples or oils shorten sample intake time and also the
purging times. Higher sample throughput can be achieved. The accessories consist of a
switching valve with a vacuum pump, and are supplied with their own control unit.
Temperature-controlled spray
chamber
The IsoMist XR temperature-controlled spray chamber has an integrated Peltier element
to bring the spray chamber to temperatures of -25 °C to +80 °C
(in steps of 1 °C).
The spray chamber is particularly suitable for organic analyses. It increases the tempera-
ture stability of the sample supply system. Cooling of the samples leads to decreased
amounts of solvent vapor in the spray chamber.
The temperature of the spray chamber is controlled via its own software included with
the accessory. Data is transmitted between the spray chamber and the PC optionally via
USB cable or wireless technology (Bluetooth).
Argon humidifier with bypass
The argon humidifier is suitable for analysis of samples with high salt content. By hu-
midifying to nebulizer gas, the argon humidifier prevents salts from crystallizing in the
nebulizer or injector and blocking it. The argon humidifier also improves signal stability
and recovery.
Argon flows over a membrane coil through deionized water and is saturated with water
vapor. Argon humidification can be switched on and off simply with the aid of the by-
pass valve without disconnecting any hoses.
Inline filter
The inline filter is suitable for analysis of samples with high solids content. The inline fil-
ter prevents solids from being deposited in the nebulizer or injector and blocking it. It
also improves signal stability and recovery.
