Water determination in all types of samples HEADSPACE OVEN AND SAMPLE CHANGER FOR COULOMETRIC KF TITRATION

Water determination in all types of samples The headspace oven technique allows the separation of the water to be titrated from liquid, solid and pasty samples. The sample is weighed in a small glass vessel with lid and septum (vial) and heated in the oven to a defined temperature. A dry air or nitrogen stream flows over a needle through the sample and takes the water with it in a gaseous state. The air or nitrogen together with the water vapour is passed into the titration vessel and the water is immediately titrated coulometrically with the T itroLine® 7500 KF trace. The headspace oven...

The TO 7280 headspace oven for semi-automatic measuring If you only have a few samples to measure per day, the semi-automatic headspace oven TO 7280 is the right choice. Why semi-automatic? The user places the sample in the oven with the flanging tongs and starts the method on the titrator or (optionally) on the TitriSoft software. Apart from entering the sample designation and, if necessary, the initial weight, this is all that Advantages of the headspace oven: needs to be done in the next few » Automatic lowering and raising of the needle head » Automatic switching on and off of the...

The TW 7650 sampler for fully automatic measuring If the number of samples exceeds 15–20/day, it is recommended to use the sample changer TW 7650. The assembly of sample changers and oven is available in less than one minute, and the sample changer is then immediately ready for use. There is no additional power supply unit or cable required. Power is supplied via the TO 7280. The user places the sample vials in the changer and starts the method/work list with the TitriSoft software. The software TitriSoft is required when using the sample changer. The sample plate rotates to the correct...
