Highly Sensitive Silica Monitor SLIA-300

Highly sensitive silica monitor for ultra-pure water management in semiconductor/FPD processes

A proven track record in silica analysis of ultra-pure water!
Compact/highly sensitive new performance.

Concentration of silica in ultra-pure water has a significant impact on product precision and yield in semiconductor/FPD processes. Reliably meeting measurement requirements of 1μg/L (1ppb). High-sensitivity measurements across the entire measurement range in a compact desktop body design have been achieved. With excellent basic performance and high sensitivity, including high-speed responsiveness and self-diagnostic capabilities, it strongly supports the ultra-pure water processes in semiconductor/FPD manufacturing.

High sensitivity with excellent repeatability

A unique newly developed cell realizes high sensitivity corresponding to low concentrations. Quick 5-minute measurements guarantee repeatability of ±2% of full scale in the 0 to 2 μg/L range.

Compact desktop design

A newly developed cell realizes a revolutionary compact design. This desktop design can be used in a variety of installation conditions, including small spaces. It is also possible to be used as a portable device.

Reagent consumption is reduced to 1/5

Adopting an improved reaction cell, the consumption of reagents has been reduced to 1/5 of conventional reagents. Running costs for reagents can be significantly reduced.

Capable of measuring up to 6 points (optional)

1 to 6 points of measurement can be freely set. A single unit can be used to support multipoint measurements.

Self-diagnostic function to monitor operational abnormalities

Self-diagnostic function detects abnormalities in operations such as sample and reagent injection, calibration errors, cell temperature monitoring, and abnormality in light source. In case of errors, a message is sent using an alarm indication lamp as well as text display to notify the user.

A maintenance-free, long-lasting light source that does not require replacement has been adopted

A monochromatic semiconductor light source with stable light intensity and long life is in use. It can be used as a semi-permanent light source.
