Clean Chemistry Tools For Atomic Spectroscopy

“The analyst must ‘think blank’. He must be aware as to the effect on the blank of every step of the analytical procedure. He must ask himself “If I do this, what is the effect on the blank?” - T. Murphy, The role of analytical blank in accurate trace analysis

Over the last few decades, developments in instrumental analysis have continuously evolved, and determination of trace elements in analytical laboratories become routine. Inductively coupled plasmas with argon gas are successfully applied for measurement of emission lines (ICP-OES) and isotopes (ICP-MS) for most elements on the periodic table. However, a laboratory must have full control of analytical blanks and sample preparation for obtaining accurate results. With detection limits reaching the ppb and ppt level, this has become even more critical.

There are many factors which may adversely affect the quality of data obtained, such as:

• The purity of the reagents
• The cleanliness of the material in contact with the sample
• The sample preparation method

With these factors in mind, Milestone has developed our Clean Chemistry line of products and accessories, aimed to reduce and control the analytical blank.
