Particles for Special Applications
 SURF-CAL
Particle Deposition Standards
Designed to simplify the preparation of particle scanner
calibration wafers in the user’s own facility.
Particles are deposited on specially selected wafers
which are then used to check the performance of particle
defect scanners at critical stages of the manufacturing
process.
SURF-CAL particles are suspended in deionised, filtered
water at a concentration of 3 x 108 particles per mL.
Particle sizes cover the entire range of interest from
0.07µm to 3.0µm. The products are ready
for use with automated deposition systems such as those
made by MSP Corporation or VLSI Standards Inc.

 HEPA-CHECK
Filter Challenge Particles
Being non-toxic and leaving no oily residue, HEPA-CHECK
solid polystyrene microspheres solve both contamination
and health risks associated with traditional DOP or
oil based filter testing.
Supplied as 25mL concentrate for dilution into one
gallon of clean water for nebulisation, particle sizes
from 0.17µm up to 0.26µm are available.

Smoke Detector Challenge Kits
for Cleanrooms
Designed for convenient testing of cleanroom smoke
alarms (e.g. to NFPA Standard 72) without the disadvantages
inherent in using oil-based sprays. The solid polymer
microspheres used in these challenge kits remove the
problem of contamination and provide a more reproducible
challenge than natural smoke.
