The main features of this range are: more safety due to py- free and one com-ponent reagents non-hazardous, fast & stable endpoints & long term titre stability. ERBAqua® One Component Volumetric Reagent In one component volumetric Karl Fisher Titration, the titrant contains all the reagents required by the reaction: iodine, sulfurdioxide, base and an alcohol. Available in to different titer strengths, 5 mg/ml and 2 mg/ml, they are suitable for routine analysis, and thanks to their methanol-free formulation, they can be used also if the sample contains aldehydes & ketones. We also provide specific working media to dissolve the sample: 570031, for sample containing oils and fats 570041, for sample containing aldehydes & ketones. It is especially suitable for high molecular weight products and non polar constituents mixture 570241 & 570251 are the one component volumetric Karl Fisher reagents, non-hazardous. DESCRIPTION SIZE CODE Karl Fischer Reagent 1 component 5 mg H2O/ml 1 lit. 570011 Karl Fischer Reagent 1 component 2 mg H2O/ml 1 lit. 570021 Karl Fischer Solvent for oils one component 1 lit. 570031 Karl Fischer Reagent for aldehydes and 1 lit. 57004 ERBAqua® Coulometric Reagent Coulometric Karl Fisher Titration method is highly effective and suitable when water content in the sample is less than 0.1% and high accuracy on the result is needed. Designed for use with all titrators and titration cell types, a wide range is available in diaphragm or a diaphramgless cell is used. For unit with a diaphragm, two reagent solutions are required an anolyte and a catolyte.

They give more accuracy in the results and longer shelf life because the reagents required by the Karl Fischer reaction are separated between the titrant (iodine) and the working medium (sulfur dioxide and base), but this implies that they must be coupled used. For general purposes, we offer two different titer strengths, 5 mg/ml and 2 mg/ml. In order to avoid side reactions in presence of aldehydes and ketones in the sample, we recommend to perform the analysis using the dedicated formulations: 570081 as titrant to be used with 570091 as working medium. For oils or other non-polar compounds, 570101 is the suitable working medium. In case of need for an extra buffering capacity of 5 mmole of acid/ml, 570121 is the suitable working medium.
