Lanwatsu passive samplers for SO2, NO2, NOx, NH3, O3

The validated reuseable Lanwatsu passive samplers for SO2, NO2, NOx, NH3 and O3 collect ambient-air pollutants at ppb level without the use of pump. They are distinguishable by color: light green (SO2), yellow (NO2), light green-yellow (NOx), white (NH3) and brown (O3). They show excelent performance in side-by-side experiment with continuos monitoring.

Lanwatsu passive samplers for HCl, HNO3, fat Carboxylic Acid

The validated reuseable Lanwatsu passive samplers for HCl, HNO3, formic and acetic acids provides monitoring the above ambient-air pollutants at ppb level. Passive sampling ambient air monitoring by using Lanwatsu passive samplers are economical alternative to active and continuos monitoring.

Lanwatsu passive samplers for BTEX

The validated reuseable Lanwatsu BTEX passive samplers allow to monitore benzene, toluene, ethylbenzene, xylene at sampling duration of 30 min to 24 hours. They are excelent economical alternative to sampler tubes for NIOSH 1501 sampling and show good correlation in side-by-side studies with NIOSH 1501 and OSHA 111, 1002, 1005 sampling using SKC and Radiello passive samplers. BTEX Lanwatsu passive samplers are ideal tool for measurement of personal exposure in working environment.
