Karl-Fischer-Titrator Aqua 40.00 with headspace module (Analytik Jena)

The Karl-Fischer-Titration can track the amount of chemically bounded and free water in materials. This technique is applicable for a huge concentration scope starting with ppm to 100 %. The headspace module heats the sample material so that apart from liquids also solid states, pasty and highly viscous materials and oils can be investigated. In addition the respective material moisture can be determined.

Scanning Mobility Particle Sizer (SMPS™) spectrometer

To determine the particle size distribution of nano particulate aerosols a scanning particle sizer (SMPS) is applied. First, fractionations of different particle sizes are generated. The fractionation bases on the particle mobility in an electrical field. Subsequently, the number of the particles in a fraction can be optically determined by the help of a condensation particle counter (CPC).

The system is highly suitable to determine the particle diameter from appr. 10 … 1000 nm and a total concentration of up to 105 particles / cm3 transient.

All non-explosive, gaseous atmospheres at standard or slightly overpressure can be analyzed. On average the results are available within 3 minutes, so that even transient processes of average speeds can be described.
