Metal Emissions Sampling Equipment

Determination of metals emissions from stationary sources is carried out by US EPA Method 29. This method may be used to determine particulate emissions in addition to the metals emissions if the prescribed procedures and precautions are followed.

A stack sample is withdrawn isokinetically from the source, particulate emissions are collected in the probe and on a heated filter, and gaseous emissions are then collected in an aqueous acidic solution of hydrogen peroxide (analyzed for all metals including Hg) and an aqueous acidic solution of potassium permanganate (analyzed only for Hg).

The collection components consist of two sets of glassware called the front half and the back half.The front half comprises of a set of glass nozzles, a heated glass lined probe, front half of the filter holder with the filter.

The back half comprises back half of the filter holder, an insulated PTFE sample transport tube and a set of 6 or 7 glass impingers housed in an impinger box in which different chemical solutions specified in the method 29 are placed.

Our PEM-MES1-X contains all the components that are required to form the back half of the collection equipment.

We manufacture all the constituents of the front half glassware including glass nozzles, heated glass lined probe (model PEM-HGLP 3), a heated filter box (model PEM-HFB2), an insulated PTFE sample transport tube.

We also make the complete filter holder and supply the filter too.

PEM-MES1-X in conjunction with these components, our Pitob Assembly comprising a Pitot Tube and K type thermocouple and one of the Control Modules PEM-SMK10 or PEM-SMK20 or PEM-SMS4 and a sampling pump module will form a complete halogens and halides sampling system.

PEM-MES1-X can also be used as an add-on to an existing Method 5 isokinetic sampling system.
