Parameters
Poor water quality affects the reprocessing of sterile goods and medical devices.
The number of outpatient clinics for operations is growing steadily in Germany. The availability of sterile instruments is essential for carrying out planned operations. The locally available water quality can vary greatly depending on the location of the medical care centre.
It is important to adapt the water treatment to the local water quality, as this cannot be transferred from one location to another.
There are 3 parameters to monitor.
1. silicate monitoring
Silicate monitoring plays a crucial role in the water treatment process for sterile medical devices in outpatient clinics.
Among other things, the water used contains silicates, which are responsible for the formation of silicate clouds and pitting corrosion on the instruments.
In order to ensure the quality of sterile medical devices and minimise the risk of infection for patients, it is essential to remove silicates from the input water as part of the water treatment process and to comply with the requirements of the DGSV guidelines and the AKI. Careful monitoring of silicate levels is therefore essential.
2. conductivity monitoring
Conductivity measurement is another important aspect of process water treatment in clinics to protect the instrumentation. The conductivity of water is a property that indicates the general quality of the water. Various dissolved substances (primarily salts) in the water are producers of conductivity, so the conductivity value is a good indicator of the purity of the water.
3. residual hardness monitoring
In addition to silicate & conductivity monitoring, residual hardness measurement is also of crucial importance. The hardness of water arises from dissolved salts, which in natural waters are mainly formed from magnesium and calcium hydrogen carbonate and sulphate, which are dissolved from the soil and/or aquifers. The concentration of salts therefore influences the hardness of the water.

Mobile Analysis Laboratory for Ion Measurements – Versatile Use Compact kit for simultaneous determination of multiple water and environmental parameters The Horiba 4M LAQUAtwin Kit is a mobile laboratory that allows you to determine important ion parameters directly on-site. The case contains pocket testers for measuring sodium, potassium, nitrate, and calcium, as well as for temperature measurement. Each device uses ion-selective electrodes for targeted analysis of small samples and provides fast, reliable results. In addition to the four measurement devices, the kit includes calibration solutions and a wash/spray bottle for sensor cleaning. The sensors can be stored dry without special storage solutions. Compact Multi-Parameter Kit for Flexible On-Site Analyses The set is designed for measurement tasks where multiple ions need to be detected simultaneously, for example when monitoring drinking and process water, performing environmental checks of water bodies, conducting aquaculture analyses, or agricultural research. Thanks to the case, all essential testers including accessories are always on hand and ready for immediate use. The measurement results are available in a short time and are reliable and reproducible – ideal for routine and control measurements in the field. All components are neatly arranged in the case and ready for use at any time. An additional advantage is that the sensors can be stored dry without special storage solutions. Due to its compact design, the kit is particularly suitable for mobile applications where multiple ion parameters need to be determined quickly one after the other or in parallel. Why Multi-Parameter Ion Measurements Are Useful – and a Mobile Kit Is Ideal In many applications, not just a single measurement is important, but the interaction of multiple ion parameters. Sodium, potassium, nitrate, and calcium together influence water quality, biological processes, plant growth, and technical operations. Single measurements in a laboratory are often time-consuming and inflexible. A mobile analysis kit allows simultaneous detection of multiple parameters directly on-site. This allows relationships to be recognized more quickly, decisions to be made more reliably, and measurement campaigns to be carried out more efficiently. The Horiba 4M LAQUAtwin Kit combines these advantages in a compact, user-friendly system.
