APPLICATION |
Cystic Fibrosis
• Only small amounts of sweat are needed
• Ready-to-use electrolyte (acid buffer and stabilization additive); complies with IVD
• Required electrolyte replacement is indicated
• Required electrode cleaning is indicated (frequent source of error)
• Reference solution 100mmol/1; complies with IVD
• GMP-compliant (Rili-Bäk, MPG) qualification and validation in hospitals and cystic fibrosis clinics
Other Applications
• The system is used both in medical laboratory diagnostics and in industry.
• Chloride determination in serum, urine, sweat or other body fluids
• Examination of food products for quality control purposes
• Water analysis of service water and wastewater
• Agricultural and ecological examinations for determination of salt content in soils
• Building material analysis in the production of cement and plaster

MEASUREMENT |
The measurement principle is based on coulometric impulse titration as an absolute measurement method, Through automated sample recognition, the measurement proceeds fully automatically after the sample is inserted without the need for manual confirmation by the user.
The end of the titration is determined by the measurement electrodes, which permanently determine the conductivity of the solution. This allows the CM20 chloride meter to be operated quickly and easily without the need for many years of experience in the classic chloride determination method. If the chloride ion concentration is very low, it is possible to raise the concentration using the standard solution.
