Contamination of an analytical sample from the laboratory environment is one of the key problems when performing trace elemental analysis at a level of tens µg/l and below. For common elements, this factor becomes crucial as their background concentrations may be very high ultimately resulting in serious errors for measuring concentration. The article describes the solution development by Analit Products – a Clean Work Space for elemental analysis. Its efficiency is estimated to reduce the probability of contamination of tested solutions from the laboratory environment. Decrease of random and bias error is proven for measurements by the example of widely distributed elements Al, Ca, Fe, Mg, Na, Si and Zn. Measurements were carried out by inductively coupled plasma atomic emission spectrometry and atomic absorption spectroscopy with electrothermal atomization.
