How to get accurate results for high matrix samples

High matrix samples can cause signal drift and plasma suppression, resulting in inaccurate results and forcing repeat analyses. The 7850’s Ultra High Matrix Introduction system uses an argon stream to dilute samples. Samples with matrix levels up to 25% TDS can be measured without time-consuming and error-prone manual dilutions. ​

The helium collision cell and half-mass correction of the 7850 automatically remove polyatomic and doubly-charged ion interferences. These functions simplify method development and remove a common cause of measurement failure.

Know more about your samples with IntelliQuant

Unusual sample matrices can cause unexpected issues. Knowing what’s in your samples allows you to avoid problems and costly sample remeasurement. The IntelliQuant software function uses the full mass spectrum to completely profile each sample’s composition. The results are displayed as a heat map, allowing you to quickly identify unexpected or abnormally high levels of elements and sample preparation mistakes. This information helps to confirm dilution factors, calibration ranges and identify possible matrix effects on internal standard elements.

The right maintenance at the right time

​Insufficient maintenance can compromise performance and cause unplanned downtime, wasting valuable time. Performing maintenance too frequently also wastes time and increases consumables costs, with no real benefit. Early maintenance feedback uses sensors and counters to determine when maintenance is needed, based on instrument usage. The traffic light color-coded alerts mean that maintenance tasks are never missed, nor performed more frequently than necessary. A well-maintained ICP-MS gives better performance and saves your lab time and money.
