Ny titreringsplatform til det moderne laboratorium: Stand-alone titratorer til coulometriske vandindhold: Enkeltparameter analysatorer til spildevand og andre vandtyper. Automated solutions from Metrohm for the determination of E10664 and TBN as well as water content according to Karl Fischer make sure that results are always in time with the customers — even when the workload is several thousand samples per day.

Electrode Finder Sample preparation Titrotherm. Vi genopfinder volumetrisk Karl Fischer-titrering: Industrial lubricants have a lot of crucial functions.
Amongst others, they reduce friction, transfer heat, transmit power, protect against wear, and prevent corrosion. Lubricant reliability relies on fast, precise and accurate analysis that complies with international standards.
Hydroxyl value in lubricants. The hydroxyl number HN indicates the amount of KOH in mg corresponding to the hydroxyl groups in 1 g sample. It is a straightforward and precise parameter to monitor degradation processes. In ester-based lubricants, the HN indicates the degree of esterification.
The method requires no boiling under reflux asgm other sample preparation steps. The method is a major benefit for laboratories that have to analyze a great number of samples per day. The additives in lubricants can react with KF reagents and falsify the result. In a KF drying oven, a stream of dry carrier gas transfers the expelled water into the titration cell.

Since the sample itself does not come into contact with the KF reagent, interfering side reactions and matrix effects can be excluded. The correct heating temperature lies below the decomposition temperature of the sample and is determined in preliminary tests.
Easily biodegradable lubricants can also be manufactured from natural fats and oils. Like the raw material, these products are also susceptible to oxidation. In lubricating oils, near-infrared spectroscopy NIRS is a viable tool for analyzing the content of aromatics, nitrogen and oil, and polycyclic aromatic hydrocarbons PAHs.
Further parameters are distillation analysis, flash point, astj point as well as density and viscosity. Applikationsnyheder, praktiske tips til laboratoriet og mere. Lubricating oil, crude oil, solvents Lubricating oil, petroleum products Insulating oil liquid.
