Kin-Tek Trace Source™ FPK Gas Permeation Tubes are used with
FlexStream™ or Span Pac™ I Gas Standards Generators to dynamically generate ppb
calibration standards of arsine in a matrix of nitrogen, air, or polymerization
grade ethylene or propylene. Concentrations from below 10ppb to over 500ppb can
be produced.
FPK Gas Permeation Tubes emit a small, steady flow of arsine
vapor that is set by the temperature of the tube. That flow is mixed in the
standards generator with a controlled flow of clean matrix gas to form the
calibration gas mixture. Mixture concentration is adjusted by changing the
matrix gas flow rate. Calibration based on the Standard Additions Principle
compensates for unknown residual arsine in the matrix gas.
Trace concentration mixtures of arsine are generally not
stable and must be dynamically generated. To minimize the hazard of working
with arsine, FPK tubes contain only vapor phase at low pressure. Conventional tubes contain the condensed
liquid analyte. FPK tubes can be totally sealed for storage and shipping so
that there is no fugitive emission of arsine.
