Main functions and features

811 Online IC online ion chromatograph monitors the entire production process
Through the 811 Online IC/821 Compact Online IC full process controller, the production process can be directly monitored:
• Improve production efficiency and capacity
• Improve product quality
• Reduce labor costs
• Shorten the downtime of the factory

Intelligent control card can quickly provide data information
The intelligent control card records the results through dedicated software for rapid reproduction of information. The analysis channel of 811 Online IC/821 Compact Online IC can continuously monitor ions in up to 10 different independent sample streams, and all limiting parameters are displayed on the instrument. Once any problem occurs, the instrument will automatically trigger the alarm system.

Flexibility and ease
811 Online IC/821 Compact Online IC is tailor-made to meet the special needs of users for any ion chromatography analysis application. The 811 Online IC/821 Compact Online IC with single channel standard configuration can measure both cations and anions;
The dual channel configuration can simultaneously measure cations and anions. By using a freely programmable sample processing program, samples can be automatically collected from the merging valves in one or 10 thoroughly cleaned channels.

The 811 Online IC/821 Compact Online IC is controlled by a built-in microcomputer and also comes with an independent uninterruptible power supply to provide continuous current. Once the system is programmed, the entire instrument is controlled by the mouse, including calling and executing calibration programs and different sample programs to analyze and monitor the large amount of ions in each sample stream. Through the integrable network, the 811 Online IC/821 Compact Online IC can output system data and remotely control it, all of which are diagnosed and serviced by the built-in modem. The calibration function and system settings are password protected, and the usage permissions and confidentiality levels can be adjusted. In fact, the 811 Online IC/821 Compact Online IC is so flexible that even non chemical professionals can operate it with ease.

English blue correction technology - unquestionable advantages
The 811 Online IC/821 Compact Online IC has a unique valve control system that can automatically calibrate anions and cations online. Using this system, the correlation coefficient of multi-point correction is better than 0.999 for ppt level analysis. For example, calibration of ions ranging from 100ppt to 500ppt.

Durable and sturdy components
The IC system itself contains mature standard components that have been used in Wantong's research grade modular ion chromatography for many years. The dual piston pump provides continuous, extremely low pulse flow rate without the need for external gas pressure. The 811 sampler is equipped with a 6-channel electronic injection valve, and chemical suppression is achieved by MSM (a durable Metrohm patented chemical suppression system). MSM has a sturdy structure and a long service life, stable compressive strength, and is very compatible with solvents. The temperature stability performance of the conductivity detector in Faraday cage is better than ± 0.01 ℃. Due to the pre amplification of data in the detector, the noise signal is reduced to a very low level, resulting in a very high sensitivity. This characteristic is particularly evident when detecting trace amounts of anions and cations in the low ppt range.

Low operation and maintenance costs
The maintenance cost required for the entire instrument system is extremely low. Because:
The lifespan of suppressors is almost unlimited and long
• Relatively low-cost rinsing solution
• Longer service life of chromatography column
The pump has a longer operating cycle
