The methods for the determination of formaldehyde and sulphur dioxide (SO2) are usually time-consuming for laboratories because the titration has to be carried out manually. However, C. Gerhardt has now automated just this time-consuming titration with the new VAPODEST 550 and the VAPODEST 550C.
Robust - Acid-resistant construction
Flexible - Integrated applications for formaldehyde and SO2
Efficient - Up to 20 samples in series (VAPODEST 550 C)
Suitable for particularly demanding applications
The acid-resistant construction guarantees consistently reliable results with low wear and tear. The automatic addition of phosphoric acid via an acid-proof pump still works with the necessary precision even after countless analytical tasks.
In addition, the VAPODEST 550 with its sophisticated design protects against accidental contact with hazardous substances.
Automation of the analytical workflow
The entire analysis process of the standard procedures for formaldehyde and sulphur dioxide determination is fully automated. Distillation, titration and the subsequent calculation of results are carried out independently by the systems. Thanks to programmed methods and titration tables specially adapted for alkaline titration, a process-optimised analysis is achieved. The automatic addition of reagents prevents, among other things, the loss of analytes.
