New Trace Gas Analyzer from Extrel Detects Down to 1amu

Related Stories

The VeraSpec Trace system from Extrel provides the ideal ionization techniques for pure gas analysis and general gas analysis in one system. Trace level analysis of impurities in pure gases is a critical capability in the development and implementation of semiconductor and other high technology industrial applications.

New technologies demand a higher standard for bulk gas purity, improved performance from purification systems, and verification of bulk gas purity at the delivery point.

The VeraSpec Trace can be configured for both electron impact ionization (EI) and Atmospheric Pressure Ionization (API) techniques, eliminating the need for two systems and significantly reducing the overall expense. The base system utilizes either the closed source electron impact ionization or the reliable DC Corona Discharge Atmospheric Pressure Ionization source. The DC Corona Discharge source is a chemical or soft ionization source that is ideal for monitoring molecules in the ppb and ppt range.

The standard EI source has detection limits in the ppb range while the membrane introduction mass spectrometry (MIMS) can provide sub ppb detection limits for some components. The VeraSpec Trace system utilizes a 19mm tri-filter quadrupole with mass ranges starting at 1 amu up to 4000 amu and is also available in an MS/MS configuration.

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
