R4 RotrOil
Rotroil with Auto Sample Changer
RotrOil rotating disc electrode OES with an automatic sample changer for higher-throughput oil-analysis laboratories.

About the R4 RotrOil
Automatize the oil analyze process and minimize the cost
GNR developed a new RDE spectrometer, RotrOil Auto Samples Changer (RTL-ASC) that provides automated operation for the analysis of the used oil samples.
It is a cost-effective instrument for un-attended operations in oil analysis laboratories, which requires considerable analysis volume.
Scope of the instrument is to support end user activity in case of several samples per day to be analyzed providing a robotizing automatic oil sample changer.
Uploaded the samples (up to 48 samples) in the carousel, R4 RotrOil, in an automatic way, is able to load oil samples, perform the spark and analysis, remove oil sample and used disc electrodes reducing preparation time for the operator and related cost per analysis.
Documented applications
- RotrOil Spectrometer could be used in correlation with ASDM norms for oil conditions monitoring and failure prevention procedure.
- Laboratories with consistent volumes could adopt the RDE automatic solution which integrate an autosampler.
- The entire automation system fulfils all the functions of sequentially introducing and removing oil samples cups and exchanging graphite electrodes.
- R4 solution make this solution very appealing to laboratories with consistent volumes.
Matrices, elements and ranges depend on the configuration supplied; EMUS confirms them in the quotation.
