 Laser
Particle Size Analysis
Thaisarco operates a Beckman Coulter
LS 13 320 Series Laser Diffraction Particle
Size Analyser for measuring particle size  distribution.
Using the Fraunhofer and Mie theories of light
scattering, the LS 13 320 Series offers the
highest resolution, reproducibility and accuracy
within the particle range of 0.04 micron to
2000 micron.
Sieve Analysis
Thaisarco uses the Octagon
2000 sieve shaker as supplied by Endecotts (UK).
The following certified sieves are available.

Apparent
Density (AD) & Flow Rate
Thaisarco uses a Hall Flow meter to
determine the flow characteristics and apparent
density of free flowing metal powders.
By interchanging the standard Hall Flow meter
funnel with the Carney Funnel, the instrument
can be adapted to determine the apparent density
of non free flowing powders (but not their flow
rate).
Determines apparent density as per ISO No. 3923/1.
Determines flow rate as per ISO No. 4490.
