The CLS-700T particle counter is a batch system used to sample process chemicals at temperatures up to 150°C. The system is designed to be versatile and fits on a laboratory cart for sampling chemicals from bath to bath within a fabrication facility. The CLS-700T chemical particle sampler extracts the fluid from a bath, drum or bottle, forces it through a sensor and collects the particle information. Sampling is performed by drawing the chemical into the buret and compressing the liquid to remove any bubbles. The wetted surfaces in the CLS-700T particle counter are chemically compatible with most hot process chemicals including hydrofluoric acid. All the electronics are physically separated from the plumbing section and purged with an inert gas to prevent corrosion. Purge gas can be provided from a house supply, bottle or pump.

The CLS 700 T chemical particle counter includes triggering which allows the sampler to be started or stopped by a process tool. The sampler can be automatically shut off during a bath change preventing the injection of damaging chemical foam and air into the particle counter.

Particle measurements are performed using the LiQuilaz chemical particle sensor. Up to 15 sizing thresholds are available starting at 0.2 microns. Sizing sensitivity is operator adjustable and controlled through the software. A personal computer is used to display the particle data in real time representing counts per unit volume in a time series plot, raw or normalized counts in a tabular format, and percent of total in a histogram.

The external surface of the CLS-700T chemical particle sampler is made out of polypropylene with all reference and status labeling laser etched. This allows for easy maintenance for wiping down between chemical sampling without damaging the surface with harsh solvents.

This particle counter is CE certified.
