Monitoring Methods used by OSHA
Laboratory Sampling/Analytical Method:
sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 microns in series with Midget Fritted Glass Bubbler (MFGB) containing 10 mL 0.1 N NaOH
maximum volume: 120 Liters maximum flow rate: 1.0 L/min
current analytical method: Ion Specific Electrode; ISE
method reference: OSHA Manual of Analytical Methods (OSHA ID-120)
method classification: Fully Validated
note: Submit as a separate sample. If present, sulfide should be listed as an interference. Particulate cyanide is collected on the filter. HCN, if present, is collected in the Midger Fritted Glass Bubbler. (See HCN) Within 1 hour after the sample has been collected, transfer the filter to a clean screw cap vial.

device: Detector Tube
manufacturer: Dräger
model/type: Cyanide 2/a, order no. 67 28791
sampling information: 10 strokes
upper measurement limit: 15 mg/m3
detection limit: approximately 1 mg/m3
overall uncertainty: 33-49%
method reference: on-site air secondary (manufacturer)
