ON-LINE TOC ANALYZER – HT-110 – HORIBA
KEY FEATURES:
Adoption of UV Oxidation Conductivity Method:
The UV oxidation conductivity method, which eliminates the need for reagents and carrier gases (purge gas), has been adopted. This method allows for high repeatability of ±2% F.S. for low-concentration ranges such as water for injection (WFI) at full scale while simultaneously providing a potential reduction in operating expenses.
Suppression of Erroneous Indications Caused by Air Bubble Inclusion:
The equipment has a deaeration mechanism, which suppresses erroneous indications caused by the inclusion of air bubbles.
External control functions:
By equipping contact input terminals, it is now possible to perform ON/OFF controls externally. Useful for situations such as false alarms during SIP cleaning or nighttime shutdown of purified water equipment.
Maintenance cycle of one year:
By significantly extending the lifespan of the UV lamp, maintenance is now reduced to a single annual calibration, allowing a maintenance-free period of one year.
Compatible with USP<643>, EP<2.2.44>, JP<G8.4.5.2>:
Suitable for TOTAL ORGANIC CARBON measurement according to USP <643>, EP <2.2.44>, and for the suitability testing of “HIGHLY PURIFIED WATER”, “WATER FOR INJECTION”, and “WATER, PURIFIED” as per EP requirements. It is also ideal for the physicochemical monitoring specified in JP <G8.4.5.2> for PW (Purified Water) and WFI (Water for Injection).
Versatile installation options:
The installation methods include pole-mounts, wall-mounts, and tabletops, allowing for flexible installation options tailored to the specific site requirements for versatile installations without limitations.
