The Spot Sampler captures fine and ultrafine particles in a concentrated manner for easy, off-line analysis. Its moderated condensational technology enlarges particles without temperature extremes, making it ideal for volatile or biological applications.
- Centerline saturation ratios reach 1.4 while maintaining temperatures below 25°C.
- Dry sample deposits measure just over 1 mm in diameter.
- High collection efficiency down to
Samples are collected as a sequence of ~1-mm diameter dry spots on a multiwall plate. Upon return to the laboratory, the plate is placed on an auto-sampler which handles all the sample extraction and HPLC or IC injection. Concentrated spots are also amenable to many analytical approaches, such as nano-DESI and LIBS, etc.
