HSLIS e-Series Liquid Particle Counters

Continuous particle monitoring in critical liquids

HSLIS e-Series is a high-sensitivity, in-situ liquid particle counter from Particle Measuring Systems. It is designed for continuous, real-time monitoring in DI water, ultrapure water, and process chemicals. The published measurement range is 0.05–1.0 µm, with four fixed channels at four model-specific channels. This configuration gives process engineers a direct view of particle changes at a distribution loop, filter, recirculating bath, chemical-delivery line, packaging operation, or point of use.

Continuous monitoring is valuable because a grab sample provides information only for one moment. An online counter can show gradual deterioration, a sudden contamination event, a filter transition, or the effect of maintenance. Trending does not automatically identify the root cause, but it provides time-correlated evidence that can be compared with pressure, flow, valve activity, chemical changes, tool operation, and maintenance records.

Flow architecture and counting interpretation

The optimum main-stream flow for this model is 100 or 300 mL/min, while the documented sample volume through the optical sensing path is 0.25, 0.6, or 3.0 mL/min. The counter measures 100% of this diverted sample volume. This statement must not be interpreted as measuring the entire process stream. Stable flow, suitable pressure control, clean tubing, correct orientation, and an appropriate installation point are required for representative results.

The maximum recommended concentration is 10,000 counts/mL. PMS states greater than 90% accuracy, corresponding to less than 10% coincidence loss, at that maximum recommended concentration. If the true concentration exceeds the specified range, multiple particles may cross the sensing region together and cause undercounting or incorrect size assignment. Bubbles can also produce optical responses, so bubble control and installation design are essential.

Technical configuration and integration

HSLIS e-Series communicates through Ethernet and provides five 4–20 mA outputs: four particle channels and one instrument-status output. RS-232 is provided for setup and diagnostics rather than normal process data. These interfaces support integration with FacilityNet, SCADA, PLC, or other plant monitoring architecture, subject to the selected configuration and engineering design.

FacilityNet can centralize multiple instruments, display real-time and historical plots, present tabular and statistical process-control information, and support excursion notifications. Alarm limits should be established from process knowledge, baseline data, measurement capability, and site risk assessment. A single generic alarm value is rarely appropriate for every chemical, location, or operating state.

Model selection and chemical compatibility

M50e provides the lowest threshold for DI water, M65e is intended for high-sensitivity chemical monitoring, and M100e extends the upper range to 1.0 µm. Selection should begin with the liquid, target size, flow conditions, temperature, and material compatibility rather than choosing only by model name. Published wetted materials are model-specific polymers, seals, fused silica, or sapphire. Compatibility must be reviewed against the exact liquid, concentration, temperature, exposure duration, cleaning agent, tubing, fittings, seals, and safety requirements. The stated sample-temperature capability does not override the lower limit of another system component.

Calibration materials are traceable to the US National Institute of Standards and Technology and/or Japanese Industrial Standards according to the PMS specification. A complete monitoring program should also define installation qualification, baseline verification, alarm review, cleaning, preventive maintenance, calibration intervals, data retention, and response to an out-of-tolerance result.
