ECH is an independent enterprise founded in 1992. The objects of the company are the development, manufacturing and marketing of analytical devices and measuring methods to analyze gas, water, industrial and municipal waste water and technical products, e.g. oil and gas.
The development of devices and methods has been successfully established for the past 20 years in national and international markets.
Important fields of applications are:
We are able to comprehend customers’ specific problems and enquiries due to our own development of the hardware and software. We response enquiries in the areas of development of new analytical measuring methods and the application of measuring devices for controlling complex and technical industrial facilities, e.g. the controlling of waste water treatment plants or the monitoring of chemical, petrochemical and bioengineered processes.
Karl-Fischer-Titrator AQUA 40.00 for
Karl-Fischer-Titrator AQUA 40.00
The AQUA 40.00 is used for microcoulometric determination of water content according to Karl-Fischer-Titration in liquid samples, solids and gases. The basic module can be expanded with additional heating modules and high sensitive closed-loop gas extraction for solids and oils. The AQUA 40.00 is designed for water determination in gases, e.g. LPG and LNG. The device allows very low background drift and short measuring times and can be used down to trace ppm-analysis.
The H2S-Analyzer can be used for determination of hydrogen sulfide in solids, gases and liquids. The determination of total volatile sulfides in aqueous solutions and oils works through high efficient gas extraction combined with a selective electrochemical detection method. Thereby, interferences from the sample-matrix are minimized. Sample preparation is not required. The device can be used in the laboratory or for online-measurements to control waste water treatment and for petrochemicals.
The portable gaschromatograph MobilGC is suitable for on-site operation, online-process monitoring and laboratory work. Its special feature is the internal gas supply, which allows the on-site use. It can be chosen between different detectors (FID, TCD, PID) according to the analytical problem. The columns are individually heated. So it is possible to adjust various temperature programs. The comfortable software allows fast and accurate analysis and various evaluation modes.
The Karl Fischer Titrator AQUA 40.00 coupled with a LPG/LNG module is designed for an easy and accurate determination of water in liquefied and pressurized gaseous samples such as LPG, DME and LNG. These device versions of AQUA 40.00 are suitable for all types of gases: flammable or inert gas as...| » Further reading
Gas extraction is the ideal method to handle oils, solid and pasty substances. The heating module for oils with closed-loop gas extraction is an extension module of AQUA 40.00. Oil samples are injected through the septum into the heating oven. It is possible to apply sample volumes ranging up to...| » Further reading
The thickness of the non-alloyed and alloyed tin layer on thin copper wires can be measured with high accuracy in a short duration by the electrochemical analyzer SnLayer. The coulometric determination of the thickness of the tin layer at the copper wires based on the newly developed multiple p...| » Further reading
