Chemical analyses

At the RMS Foundation we can offer you the following services in the area of chemical testing:

Identification/quantification of organic compounds


Various methods can be offered for the identification or quantification of organic/carbon-based compounds (also in complex matrices):


  • Material impurities, foreign substances
  • Additives (e.g. plasticizers in polymers)
  • Incoming goods inspection and quality control
  • Composition of products (competitive analyses)
  • etc.

Contact us and we will discuss your individual questions.

Standard(s): various
  • Fourier transform infrared / FTIR microscopy (NL-21)
  • Determination of the cleanliness of medical devices (NL-31)
  • TOC/TIC/TN: Quantitative analysis of dissolved organic and/or inorganic carbon as well as nitrogen (NL-36)
Equipment: GC-MS/MS, TOC, TIC, TN, FT-IR



Microcalorimetric measurements on solutions and solids


Measurement of heat released by a chemical and/or physical reaction to determine thermodynamic properties of solutions and solids. The resulting heat flow data in the milliwatt range and under isothermal conditions are continuously plotted as a function of time. Injection and mixing of liquids under isothermal conditions is possible during the measurement, e.g. to investigate initial phases of a cement reaction.

Standard(s): Not accredited
Equipment: Calorimeter (isothermal) TAM Air 3115/3238 with injection ampoule Admix



Residual moisture content

Description: Determination of the residual moisture content via weight loss after intensive drying according to Ph. Eur. Monograph 2.2.32. "Loss on drying" 01/2008:20232.
Standard(s): Ph. Eur. Monographie 2.2.32
Equipment: Drying oven Memmert type ULP 500 and UFP 500 / Precision balance Mettler Toledo AX205

Titrimetric analyses

Description: Calculation of an unknown quantity of a dissolved substance after reaction with a reagent solution and exact measurement of the volume of the consumed reagent solution and consideration of the content of the active substance. The substance to be determined is quantitatively transferred from a chemically precisely defined initial state to an equally defined final state.
Standard(s): not accredited
Equipment: Metrohm Titrando 907



Determination of the pH value

Description: Determination of the acidity or alkalinity (pH value between 0 and 14) of an aqueous solution.
Standard(s): DIN 19268
Equipment: Metrohm Titrando 907



Density determination of solids and liquids


Density determination according to Archimedes' principle (measurement of buoyancy force). The density of a solid is determined with the aid of a liquid whose density is known. The solid is weighed once in air and then in the auxiliary liquid. The density can be calculated from the two weighings.
The density of a liquid is determined using a displacer whose volume is known. The displacer is weighed once in air and then in the liquid whose density is to be determined. The density can be calculated from the two weighings.

Equipment: Analytical balance Mettler Toledo XS205DU with density measuring kit
