This paper examines the opportunities in DI water particle monitoring to improve performance, track data trends, and reduce cost by using a combination of high sensitivity particle counters and less expensive, lower sensitivity (0.1 microns) particle counters with very high sample volumes. We detail the impact of size sensitivity, sample volume, and zero count level on DI water particle counter performance. Practical monitoring considerations and particle distribution differences between poorly filtered and highly filtered DI water systems are also covered.

This paper was written to outline the communication requirements as applied to a CLS-700T particle counter and LiQuilaz particle counter combination. Both particle counters must be communicated separately via different network addresses. The CLS-700 particle counter employs hardware lines to control when the LiQuilaz particle counter is actively sampling. Only the CLS-700T particle counter command/response sequence pairs are described in detail. |
