Products Information

KulTech Incorporated has developed a method for preparing samples using aerosol deposition of particulate matter (PM) /metals for air sampling analysis. These samples are collected by a process comparable to ambient-air field sampling. A batch of test filters is prepared by sampling aerosols from a chamber containing a known amount of analytes. A statistically significant number of samples from each batch are analyzed by referee laboratories.

Aerosol Deposition
Aerosol Generator for Research applications is a dynamic system and is based on producing an atmosphere of constant aerosol concentration. Combining two simultaneously generated aerosol streams in the reaction vessel, or successive depositions of aerosol on filters opens a entirely new area for research. Stabilizing Chromium (Cr +6) well as mercury (Hg+2) on filters at low concentrations has been achieved.

EC-OC PE Samples
Elemental carbon (EC) and organic Carbon (OC) samples which give reproducible EC-OC and TC (total carbon) values by both the NIOSH Method 5040 and IMPROVE protocols used in Thermal Optical Analysis (TOA) are available. In addition to being used for performance evaluation, these samples can be used as check samples for TOA instrumentation. Scanning Electron Microscopy indicates particle sizes of approximately 1 micron.

Metal PE Samples
Aerosol deposition technology is used to prepare uniformly deposited PE samples with desired combination of analytes in wide range of concentrations ( 10 nG to 1000 µG) Samples prepared on PTFE (Teflon®) filters can be used for calibration of ED-XRF instrumentation. ICP-MS performance samples on quartz filters are being used in EPA’s air sampling program for ambient air analysis.  The quartz samples also can be used as calibration check samples for WD-XRF.
