Trace Elemantal Analysis


Trace Elemental Analysis (TEA) is a group of analytical techniques that are very important in Environmental Analysis, Metallurgy, Food & Beverage and Pharmaceutical industries. Using Trace Elemental Analysis, most of the elements of the Periodic Table can be determined in a very broad range of solid, liquid and gaseous samples. This is done with a variety of analytical methods.

  • Inductively Coupled Plasma (ICP-OES, ICP-MS)
  • Total Organic Halogen (TOX)
  • Carbon, Nitrogen (TOC, TN)
  • Atomic Absorption Spectrometry (AAS)
  • A variety of elemental analysis to determine Carbon, Hydrogen, Nitrogen, Sulfur and Oxygen (CHNS or CHNOS)

Examples of applications

  • Mass Flow Controllers (MFC) supplying carrier gas flow in CHNS, TN, TOX, TOC and several other analysers
  • Flow control of plasma gas in ICP
  • Flow control of nebulizer, auxiliary/sheath and purge gases in ICP
  • Collision/Reaction Cell gas flow control
  • Gas flow control in AAS with safety line for burner system

Flow control for analysers

An important function within analysers that are based on these methods is the flow control of different gas streams: carrier gas, plasma gas, nebulizer gas, purge gas, burner gas and sample gas streams. Bronkhorst supports Original Equipment Manufacturers (OEM) in the field of Trace Elemental Analysis with customized flow solutions, which are compact, economical, accurate, reliable and provided with the desired interfacing.

Gas supply in Inductively Coupled Plasma (ICP-AES)

Inductively coupled plasma (ICP-OES, ICP-AES) analysers are used to analyze the quantity of trace elements in several matrices. Flow meters play an important role in this equipment.

The trend towards miniaturization in flow solutions

The footprint/benchmark of an analyser is important in the limited space in a laboratory. Also analysers are more-over used as point-of-care solutions. Analysers become smaller and smaller and therefore the flow solutions need to become smaller as well.
