Sample introduction: Vapor generator
|
The HG3000 Hydride generator forms part of a complete hydride system which can be used in conjunction with any GBC AAS for trace level analysis of the hydride forming elements (arsenic, selenium, bismuth, germanium, antimony, tin and tellurium), and mercury by the cold vapour method. Detection limits of 1 ppb are routinely achievable. Typical sample throughput is around 60 samples per hour taking three replicate measurements, with a typical precision of 1%.
The quartz cell used for hydride analysis can be heated by flame, or by the optional EHG3000 electric cell heater. The EHG3000 provides a temperature controlled electric heating blanket to heat the quartz cell, and includes power supply, temperature controller and workhead. The EHG3000 provides more accurate temperature control than is possible with flame heating.
