Introduction PMS Ultra DI 20 Plus Liquid Optical Particle Counter
Sensitivity range: 20 – 100 nm
Designed specifically for ultrapure water systems, the Ultra DI 20 Plus Liquid Particle Counter from Particle Measuring Systems PMS quickly obtains statistically meaningful data and will count and size contaminants as small as 20 nm. Consistency helps you get more out of your data, even if the instrument moves, so you have more control over your process. The Ultra DI 20 Liquid Particle Counter has a low zero count, large sample volume, and high counting efficiency that provides benchmark particle detection. Improved sensitivity allows you to detect process variations more quickly with 20 nm polystyrene latex (PSL) and 9 nm gold (Au).
Particle Measuring Systems (PMS) is the world leader in sensitivity.
Features Ultra DI 20 Plus
- Unmatched instrument to instrument data stability and matching with thermally stabilized measurements of particles across a 18 to 29°C operating environment
- Instrument to instrument matching within 20% at concentrations of < 10 particles per ml
- Compare UPW system performance across multiple fabs in any environmental conditions anywhere in the world
- Fleet can be swapped without disruptions or questions about the data
- Two counting modes
- High resolution – for pure environments
- High concentration – for filter challenge tests and lower purity environments
- Connect directly to PLC and SCADA systems with 4-20 mA and utilize the existing network with Ethernet communication
Benefits Ultra DI 20 Plus
- Advanced laser optics and sensors enable the detection of particles down to 20 nm (9 nm Au)
- Quickly obtain meaningful statistical data to detect particle excursions and troubleshoot problems
- Fast sample cleanup shortens the time to move from one sample point to another
- Respond immediately to contamination with real-time particle measurement
- Eliminates the additional purchase price and maintenance cost for an environmental enclosure
Applications
- Quantifying particle concentration in state-of-the-art ultrapure water (UPW) systems
- Filter efficiency measurements
- Trending analysis at lower particle concentrations
- Detecting bacterial growth in ultrapure water (UPW) systems
- Episodic event tracking and alarming
- Continuous system monitoring
