Example
Problem:
Impurities in polymerization grade
Ethylene and propylene.
Ethylene and propylene producers are primarily faced with product
concerns. The most common impurities (see Table 1) are monitored both on-line for process control
and in the
laboratory for product quality.

| COS | H2S | Total Sulfurs | Ethylene | |
| Propylene | Arsine | CO | CO2 | |
| Acetylene | Methanol | Other Oxygenates | H2O | |
Solution: KIN-TEK's
FlexStream™ and 491M Series Laboratory
Standards
Generator or Span Pac™ I Series Industrial
Standards
Generator provide calibration
standards for all these compounds, using KIN-TEK's NIST-traceable Trace
Source™ disposable or refillable permeation
tubes.
Benefits include:
- The standards are generated fresh, eliminating the storage/deterioration problem inherent in gas cyclinders..
- KIN-TEK's permeation tubes improve the accuracy of the analysis.
- Our instruments easily generate span gases for span checks or multi-point calibrations.
