Using CheckPoint* Pharma and CheckpointeOnline and portable Total Organic Carbon (TOC) sensors can measure low levels of TOC anytime, anywhere. The multi-functional and super portable CheckPoint sensor that users can afford can be used for online continuous monitoring or carried to any point in the water system for rapid diagnosis, sampling, and troubleshooting.

Except for the following points, the specifications of the two Checkpoint models are the same:

• The dynamic range of CheckPoint Pharma is 0.21―1000 ppb. Can measure hot water or water containing ozone. Meets the requirements of the pharmacopoeias of the United States, Europe, China, and India.

• CheckPointeDesigned to meet higher sensitivity requirements in semiconductor, power, and other markets, with a dynamic range of 0.05―1000 ppb.

0. Key advantages

   Save costs―The CheckPoint sensor uses a simple TOC detection method to measure the initial sample conductivity, UV oxidation of organic matter, and finally the conductivity after UV oxidation (direct conductivity method). This provides a reliable and low-cost TOC method for purified water (PW) for pharmaceutical use, water for injection (WFI), and semiconductor ultrapure water (UPW).

   Quick analysis―For time sensitive diagnosis and troubleshooting, two sensors provide fast results and fast flushing time. The default measurement time is 15 seconds, and users can adjust the output time interval from 15 seconds to 8 hours.

   Fully functional and easy to use―Sensors can be used for continuous online monitoring, rapid online monitoring, or sample collection. It also has digital communication capabilities, including Ethernet (Modbus TCP/IP) and a USB port for easy data download.

   Low maintenance, easy to use―CheckPoint requires no reagents, is easy to operate, and only requires minimal maintenance.
   Matching between sensors―The sensor can be calibrated based on the reference TOC instrument to achieve excellent matching between low content TOC sensors and sensors.

Pharmaceutical―CheckPoint Pharma provides pharmaceutical manufacturers with cost-effective and flexible process monitoring for process trends, screening potential problem areas, and diagnosing problems in real-time. CheckPoint Pharma can be placed in dedicated usage points or used for multi-point water quality monitoring, diagnosis, and troubleshooting at various locations in pharmaceutical production facilities. Check Point Pharma comes with a simple and convenient Standard Operating Procedure (SOP) that meets the requirements of Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).

Hard drives, thin displays, and semiconductors―CheckPointeThe low cost and portability provide microelectronics manufacturers with new problem-solving and diagnostic capabilities. In addition to providing continuous online TOC monitoring to detect crucial changes in ultrapure water, CheckPointeSensors can also perform rapid TOC detection on water samples from pressurized or non pressurized water sources. CheckPointeIt can also monitor the distribution points of ultrapure water (UPW) or potential sources of pollution in microelectronic manufacturing factories. Electricity (ultra pure water, cation conductivity control, supply water, thermoelectric co condensation water precision treatment control)―CheckPointeProvide highly sensitive detection of trace organic pollutants in electric water supply and circulating ultrapure water. If the cation source is a non-ionic organic compound, it will be very difficult to control the cation conductivity. The high pressure and temperature in the water cycle of power facilities can oxidize non-ionic organic compounds such as Cl, S, or N into highly corrosive hydrochloric acid, sulfuric acid, or nitric acid. CheckPointeIt has a strong response to these compounds and can quickly indicate their presence in make-up or condensate water. CheckPointeThe super portability and diagnostic features also make it very easy to quickly detect other issues with ultrapure water systems.
