Accurate measurement of particulate matter is essential in cleanroom monitoring across pharmaceutical, life science, aerospace, defence, and semiconductor manufacturing as well as food and beverage environments where air, surface, or liquid contamination is a concern and requires diligent monitoring.
Thermo Scientific™ Count Controls provide a comprehensive solution for calibrating and validating laser particle counters to ensure accurate results. Our Count Controls enable users to validate the accuracy of their particle counters, regardless of the brand they are using. By using our solution, you can have confidence that your instrument is measuring particulate matter correctly, avoiding potentially misleading and inconsistent data that could lead to costly and time-consuming errors.
Our Count Controls have a diameter that can be traced back to the National Institute of Standards and Technology (NIST) and provide the necessary documentation and assurance required by quality control (QC) processes. They are designed to help maintain cleanrooms and ensure that they meet stringent protocols, including the ISO 14644-1:2015, ISO 14644-2:2015, and ISO 14644-3:2019 standards. These standards involve the classification of air cleanliness by particle concentration, specifications for testing and monitoring to demonstrate ongoing compliance, and guidance on the instrumentation to be used for testing compliance with ISO 14644-1.
Our Count Controls are supplied as a low residue aqueous suspension, minimising background interference and allowing for precise insight into the dynamic range and calibration of the instrument.
The Thermo Scientific 3K/4K Series Particle Counter Standards ensure accurate and convenient calibration of laser particle counters. This product line is specifically designed for immediate use in laser particle counters, reducing the need for time-consuming concentration adjustments.
Document the reproducibility of a particle counter by permitting a continuous record of its performance with Thermo Scientific™ PHARM-TROL™ Count Precision Size Standards.
Minimise contamination by eliminating the need for serial dilutions and extensive sample handling with Thermo Scientific™ COUNT-CAL™ Count Precision Size Standards, a cost-effective, convenient and easy to use product for validating liquid particle counters.
Packaged in single-use bottles and intended to be sampled directly from the bottle, standards were developed for manufacturers of parenteral drugs and ophthalmic solutions seeking interim verification of USP 788 and 789 (Particulate Matter in Injections and Particulate Matter in Ophthalmic Solutions).
Ready to use precision size standards are designed for regular use in liquid particle counters to verify instrument calibration before each use, assuring the reproducibility of the particle counter by permitting a continuous record of its performance using a NIST™ traceable microsphere suspension with a precise concentration.
Meet the unique and demanding requirements of the contamination control laboratory in modern industries with Thermo Scientific™ Ezy-Cal™ Count Precision Size Standards, easy-to-use liquid particle count controls at 2000 particles per mL. Designed for regular use in liquid particle counters to verify instrument calibration before each use, standards assure reproducibility of the particle counter by permitting a continuous record of its performance using a NIST™-traceable microsphere suspension with a precise concentration.
Validate the performance of liquid particle counters with Thermo Scientific™ Validex™ Count Precision Size Standards. Excellent for instrument calibration and verification in the drinking water industry and for low level liquid particle counting and calibration, standards contain NIST™-traceable polymer particles packaged in ultrapure water at concentrations ideal for use in validating the performance of liquid particle counters.
Particle counting in the drinking water industry has rapidly become an indispensable technology for optimising water quality. The majority of particle counters used in the drinking water industry operate on the principle of single particle light obscuration.
