The Solu-Sert™ filter capsule is a self-contained filter “cassette capsule” that captures all particles collected by a filter cassette.

The Solu-Sert™ filter capsule is a self-contained filter “cassette capsule” that captures all particles collected by a filter cassette. It consists of an MCE filter membrane sealed to a cellulose shell to create the capsule. This capsule is then inserted into a Zefon 2-Piece filter cassette with a support pad as a complete unit. After sampling the entire capsule is removed, digested in an acid solution, and then analysis performed. This process eliminates the need to rinse or wipe the cassette interior to account for "wall deposits" and makes it ideal for performing airborne metals analysis.
Features:
- Contains 100% of the sample collected within the capsule.
- Meets NIOSH requirements for including "wall deposits" as part of the sample.
- Suitable for use in 15 NIOSH methods (listed below).
- Easy laboratory processing with NO rinsing or wiping.
- Lightweight shell design contributes to less background and improved limits of detection vs using a heavier weight shell.
How it works
Air flows into the filter cassette through the inlet and continues into the Solu-Sert™. Particulate is then contained within the Solu-Sert™ while the airflow continues through the filter membrane and exits out the cassette outlet.
Applications
Solu-Sert™ is suitable for collecting the following contaminants:
| Contaminant | NIOSH Method |
| Aluminum | 7013 |
| Arsenic | 7900 |
| Barium | 7046 |
| Beryllium | 7102 |
| Cadmium | 7048 |
| Chromium | 7024 |
| Cobalt | 7027 |
| Copper | 7029 |
| Elements | 7300, 7301, 7303 |
| Lead | 7082 & 7105 (note) |
| Tungsten | 7074 |
| Zinc | 7030 |
(Note Blanks may have to be determined prior to analysis)
Solu-Serts have been shown to exhibit background levels at or below the detection limit of 25 elements. Measurable background levels of Ca, Mg and P, have been detected, however these levels are not significant in relation to the Occupational Exposure Limit (OEL) for e.g., Ca, (OH)2, MgO or H3PO4. (Background levels as presented by NIOSH in "NIOSH Guidelines for Aerosol Sampling", Pg 33).
PLEASE NOTE that Solu-Sert™ is not appropriate for gravimetric analysis. Due to the hygroscopic nature of cellulose, tare weights will not be reproducible. For gravimetric analysis using a cassette capsule, use the Zefon Gravi-Sert.
