ULTRA Sampler Sorbent, Anasorb GCB1 in a Vial, 370 mg Overview

ULTRA Sorbent Vials for User-filled Samplers, contain Anasorb GCB1 (comparable to Carbopack B), 60/80 mesh, 370 mg each vial, limited shelf-life, require empty housing Cat. No. 690-200, Qty/2

Storage at  ≤ 39.2 F (4 C) required.

The ULTRA® Passive Sampler offers a choice of four sorbents for environmental air sampling. The ULTRA samples by diffusion and provides low ppb to ppt detection of compounds, including semi-volatile organic compounds (SVOCs). Use the ULTRA as an alternative to stainless steel canisters for green building certification, fenceline monitoring, product emissions, vapor intrusion, and near roadway, traffic, public health/asthma, and school zone studies.

 

Applications

  • Public health/asthma studies
  • Near roadway air quality studies
  • Volatiles from soil gas, biological sources, and water
  • Traffic studies
  • Fenceline monitoring
  • Monitoring pollution migration from industrial processes
  • Odor profiling in fragrance, food, and flavor industries
  • Product emissions
  • Emergency response to oil spills and leaks
  • Green Building certification
  • Vapor intrusion
  • School zone studies


 

 

Performance Profile

Sampling Media Choose from 5 sorbents
Sampling Rate Dependent on compound of interest (validated rates available)
Sample Time Varies with sorbent, analyte, and detection limit
Sample Pump None required
Analysis Thermal desorption (TD) with gas chromatography/mass spectrometry (GC/MS)

SKC introduces ULTRA Passive Samplers — the creative evolution of indoor and ambient air sampling. The patented* ULTRA samples by diffusion and provides low ppb to ppt detection of compounds, including semi-volatile organic compounds (SVOCs). ULTRA Passive Samplers are an economical alternative to stainless steel canisters for EPA TO-15 sampling and show excellent sampling correlation in side-by-side studies with canisters. Operation is as easy as sliding the cover open to start sampling and closing it to stop sampling. ULTRA Passive Samplers are also a convenient alternative to and have a higher uptake rate than thermal desorption tubes

* U.S. Patent No. 6,607,581

Side-by-side performance studies show excellent sampling correlations between ULTRA samplers and stainless steel canisters. Compare and see that ULTRA passive samplers are the economical, convenient alternative to stainless steel canisters.

* MRL — minimum reporting level: These can vary with each laboratory; check with the laboratory.
• Indoor — low velocity conditions (< 5 cm/sec)
† Outdoor — 5 to 200 cm/sec, low air velocities, typically found in indoor air, result in lower uptake rates in passive samplers
