Ultraclean Chemistry Line

Complete line for control and reduction of the analytical blank

Analytical chemists continue to advance the performance of trace and ultra-trace elemental analysis. Multi-element analyses of trace metals at ppb or ppt levels are routinely performed by ICP-AES and ICP-MS.
There is a growing awareness that sample handling and preparation must evolve to meet the same exacting standards as these instrumental techniques.
There are a number of external factors that can critically impact the quality of the data. Factors that are well within the control of the modern chemist include:

Reagent purity

The sample preparation method

The materials that come in contact with the sample during preparation

The environment in which the samples are prepared

Sample to sample cross contamination

Each of these factors, in one way or another, is related to the analytical blank: its chemical composition, its measurement, and its effective control.
As analytical chemists are well aware, when working at ppb and ppt levels, constituents of the blank contribute not only to the measured signal but also to the error in the blank.
This uncertainty contributes to the overall error of the sample measurement.
To address these issues, Milestone has developed "The UltraCLEAN Chemistry" line of products to support Clean Chemistry Sample Preparation.

Problems for blank control	Status	Milestone Unit
1 - Acid purification		DuoPUR
2 - Ultratrace cleaning of vessels and instrument component		TraceCLEAN
3 - Contamination from vessel surface		Quartz/TFM Inserts
4 - Sample preparation method		Labstation for closed vessel digestion
5 - Sample evaporation without element losses		MMR Rotor line

The inability to control the analytical blank is often the primary source of error and the limiting factor for trace analysis
