Cleaning for Trace Analysis
Microlit Lentus™ – Hydrofluoric acid dispenser can also be used for Trace Analysis. The precise volume dispensing of high-purity media makes the HF dispenser suitable for this application. To use a hydrofluoric acid dispenser for trace analysis, it should be first thoroughly cleaned. Pure chemicals used for analytical purposes are used for this cleaning procedure. In order to avoid contamination of the bottle contents, the HF dispenser with the recirculation valve must be cleaned in both dispensing and recirculation modes.
To use the hydrofluoric acid dispenser for trace analysis, perform cleaning thoroughly first with pure chemicals like acetone, 20% HCl, and 30% HNO3 and lastly with de-ionized water. For the detailed procedure, please refer to the Microlit Lentus instruction manual– Cleaning for Trace Analysis section.

The error limits (Accuracy and Coefficient of Variation) mentioned above are in accordance
with the nominal capacity (or maximum volume) indicated on the instrument. These are obtained by using the instrument with distilled water at equilibrium, the ambient temperature of 20 °C while operating it smoothly and steadily. The error limits are in accordance with DIN EN ISO 8655-5.
