The 10.547 has replaced its well-established and successful predecessor 10.537 offline sampling system.

Manufacture: P S Analytical
Model: PSA 10.547

The unit is semi-portable so it can be easily transported between sample points or moved to test different locations. It can also be installed on a permanent basis by mounting to a wall or free standing frame. It may also be put into a 19 inch rack cabinet for additional environment protection if needed. The sampling system can be used for any type of gas and it may be used in hazardous area locations. The unit contains Ex d components with ATEX and IECEx certifications, the system classification is Ex d IIC T3. The sampling system is connected to the sample point using a filter and appropriate length of stainless steel braided Teflon hose. A high flow primary bypass is used to ensure that a representative sample is obtained and prevent losses of mercury on upstream sampling components. A Rotameter can be used to get this flow or a Primary Bypass Control Kit can be installed for permanent installation. The depressurized sample is then passed over two Amasil gold traps which can be mounted in series to comply with ISO 6978:B and ASTM 6350 or in parallel mode. The sample flow is controlled using a flow meter and the volume of gas passed over the Amasil traps is recorded using a dry or wet gas meter. Once the gas sample has been collected, the traps are returned to the laboratory to be analysed using the PSA 10.525 Sir Galahad mercury analyser. The Amasil traps will collect all forms of mercury so the measurement corresponds to total gaseous mercury.  The system is designed to have low carryover of mercury by using components with low affinity for mercury. A specially coated version is also available 10.547/110V/C or 10.547/230V/C for customers who encounter wide Hg concentration ranges.
