USE AND APPLICATIONS IN
HEALTH & SAFETY
Kanomax OPCs from SKC are available with either 3 or 5 channels.
Each channel represents a size range in which total particle numbers are measured, stored, and displayed on the LCD screen.OPTICAL PARTICLE COUNTERS
SKC Cat. No. 745-3886
SKC Cat. No. 745-3887
This technology allows smaller size particles to be measured.
A CPC can measure particles as small as 15 nm.
They can detect particles as large as 1 µm in size.CONDENSATION PARTICLE COUNTERS (CPCs)
SKC Cat. No. 745-3800
2. To determine if control measures are effective in reducing nanoparticle exposures.
Sampling for nanos may be done for production/quality reasons along with health and safety concerns.
Nano-enabled materials are expensive, so manufacturers do not want these materials escaping from the production process into the work environment.MEASURING NANOPARTICLELEVELS: WHY?
NIOSH recommends the use of:
a) Direct-reading particle counters
b) Filter samples with lab analysis
To obtain key particle metrics including:
What do you do with this data?
Take measurements with BOTH an OPC and a CPC.
NIOSH field studies
background levels of
1246 to 19,500
Note any unusual
conditions in test
environment that could
impact the background
levels.EVALUATING NANOS: NIOSH EMISSION ASSESSMENT TECHNIQUE
But, you only get one particle count with this instrument
1.0 µm is the largest particle size detected.CPC VS. OPC: WHY 2 PARTICLE COUNTERS FOR NANOS?
It can only detect particle sizes down to 300 nm,but can detect larger particles (agglomerates) up to 5 µm.CPC VS. OPC: WHY 2 PARTICLE COUNTERS FOR NANOS?
Particle counters use laser technology to count individual particles.ARE PARTICLE COUNTERS SIMILAR TO HAZ-DUST INSTRUMENTS?
This means 9.53 X 105 particles/air volume
