Air-Cooled Mercury Probe Accessories

Apex Heated Mercury Sorbent Trap Probes are designed to accept a pair of standard 10 mm O.D. sorbent traps. The sorbent traps are placed at the probe inlet to prevent Hg transport losses during sampling. The traps are sealed in place with compression fittings using glass-filled PTFE ferrules. The probe is constructed from corrosion resistant tubing; the outer sheath is 2” O.D. and the inner liners are ½”. Alloy C276 is recommended for XC-6000 applications due the constant exposure to possible corrosive stack environments. Stainless steel probes are available for short term testing such as method 30B applications The probe is fitted with two heaters; one to heat the traps and the second for heating the portion outside of the stack. Standard lengths are available from 4 to 12 ft. long. Alternate lengths are available upon request.
