DESCRIPTION |
Liquid Particle Count |
Particle Measurement Systems Liquilaz instrument detects
and counts water-born particles over 0.25µm in
size in 6 discrete size bins. Particles are extracted
from parts using 68kHz ultra-sonic excitation at prescribed
power levels, water temperature and dissolved oxygen
content. |

|
| Ion Chromatography |
Dionex Ion Chromatograph detects
the solution anions and cations present on parts and classifies,
by ion, the weight present which is then calculated into nanograms/cm2
using the surface area of the parts and total sample volume |
| Temperature and Humidity |
Tenney Temperature and Humidity
chamber capable of 85°C and 85% relative humidity for environmental
stress testing. Four-corner tests can be run with repeated cycles. |
| Passivation |
Our lab conducts Mil-Std 753
Method 103 and ASTM 967-01, Practice D (Copper Sulfate) or Practice
E (Potassium Ferricyanide) testing to assess the suitability
of the passivation layer of stainless steel products. |
| Hard Particle Analysis (HPA) |
JEOL scanning electron microscope
equipped with EDAX energy dispersive spectroscopy system using
automated stages and contrast filters to identify particles
of material different than the parent part at high magnification
(typically 500X-1000X). Software collects the size, aspect ratio
and composition of each particle in a pre-set pattern of areas
on the surface |
| Liquid Particle Analysis (LPA) |
Similar to HPA, analyzes particle
present in the effluent from a Liquid Particle Count (LPC) extraction
filtered through a 0.2µm MIlipore filter. The filter is
then dried and coated for SEM inspection. The results address
the basic question of “What makes up the particles in
an LPC extraction?” |
