The TE-290-MY are 34mm diameter Mylar collection substrates specifically designed for use with the TE-298 Marple Personal Cascade Impactor's 6-stage configuration. These lightweight collection media enable accurate aerodynamic particle size distribution measurements from personal exposure monitoring applications. Each package contains 100 pre-cut substrates ready for installation in the impactor stages.
Mylar substrates offer electrostatic particle collection properties that enhance capture efficiency for charged aerosol particles. The smooth, non-fibrous surface minimizes particle bounce while maintaining measurement accuracy across the impactor's size range. These substrates provide reliable particle collection without the need for grease coating, simplifying handling and post-sampling analysis.
Key Specifications
- Diameter: 34mm
- Material: Mylar (polyethylene terephthalate film)
- Configuration: 6-slot pattern
- Package quantity: 100 substrates
- Thickness: Optimized for minimal interference with impactor jet flow
Compatibility
These substrates are designed for the TE-298 Marple Personal Cascade Impactor operated at 2 LPM flow rate. The 6-slot configuration matches impactor stages with cut-points of 9.8, 6.0, 3.5, 1.55, 0.93, and 0.52 microns. Compatible with personal sampling pumps in the 0.5-5 liter range, though optimal performance occurs at the standard 2 LPM sampling rate.
Sampling Applications
Ideal for personal exposure assessment in occupational health monitoring, workplace aerosol characterization, and environmental health studies. The personal cascade impactor provides complete and accurate aerodynamic particle size distributions of particulate in the worker's breathing zone. Substrates support gravimetric analysis after collection for mass-based particle size distribution determination.
Handling and Maintenance
Prior to sampling, substrates must be pre-weighed and carefully placed in each impactor stage using clean tweezers. After sampling, substrates are reweighed to determine collected particle mass, with the weight increase providing mass distribution data across size ranges. Store substrates in a clean, dry environment to prevent contamination before use.
