A method for mercury analyzer sample chamber sealed

Description: A method for mercury analyzer sample chamber is sealed, and relates to a technique mercury analyzer sample chamber for sealing. Provides an easy to operate, can be reused, do not contaminate the sample, mercury analyzer sample chamber sealing methods. In the mercury analyzer quartz glass cuvette ground plane and between ports of stainless steel as an electrode contact assembly plane located a hollow ring gasket, the gasket with inner and outer diameter quartz glass cuvette grinding mouth, thickness 0.1 ~ 1.0MM. Gasket material may be a polymer gasket, metal gasket, or soft graphite gasket. Instead of using the gasket sealing the sample chamber vacuum grease to achieve, because the gasket is a solid sheet of regular shape, with good deformation and buffering capacity, simple, does not pollute the samples, but the gasket can be reused. Further, since the spacer thickness and the diameter control, and therefore the injection is relatively stable in the mercury mass, to improve the accuracy and precision of the test. At the same time safe and reliable, to avoid sample cell rupture.
