Introduction

The SKC Hydrogen Cyanide (HCN) Passive Sampler, speciﬁ ed in OSHA Method

1015, provides accurate sampling of hydrogen cyanide from 0.44 to 20 ppm for

either 15-minute or 8-hour samples. The uptake rate for the HCN Passive Sampler

is 28.4 ml/min. The sampler design allows the user to load 600 mg of soda lime

sorbent (supplied in a vial) into the sampler housing in the ﬁ eld immediately before

sampling and transfer the sorbent from sampler to vial in the ﬁ eld immediately

a er sampling as speciﬁ ed in the method. Samples are desorbed with water and

analyzed by ion chromatography/electrochemical detector. The HCN Passive

Sampler is designed for single use.

Performance Proﬁ le

Sorbent/Amount: Soda Lime, 600 mg (supplied in glass vial)

Housing Material: Nylon

Diameter: 1.4 in (3.5 cm)

Length

(including clip): 2.5 in (6.3 cm)

Measuring Range: 0.44 to 20 ppm

Analysis: Solvent extraction; ion chromatography (IC) with electro-

chemical detector (ELCM)

Sample Storage: 3 weeks at 68 F (20 C) in storage studies

Note: OSHA Method 1015 recommends that samples be sent

to a laboratory as soon as possible. If delay is unavoidable, store

samples in a refrigerator as a precaution.

Sample Time: Validated for 15 min and 8 hrs

Sampling Rate: 28.4 ml/min (4.40% RSD)

Sampling Remove sampler housing and vial of sorbent from resealable aluminized pouch. 2 Write pertinent information, including Sample ID#, on the lines provided on the pouch label and the sampler housing. 2 Note: OSHA Method 1015 specifies that the sample site temperature and uncorrected atmospheric pressure be recorded. Soda lime sorbent is very caustic. Wear gloves when handling sampler and vial to avoid skin contact with sorbent. Perform this step immediately before sampling or on the day of use.

Write stop time on pouch and sampler label. Soda lime sorbent is very caustic. Wear gloves when handling sampler and vial to avoid skin contact with sorbent. 8A Vial Adapter t ben Sor Perform this step immediately after sampling. In a clean environment, free of hydrogen cyanide and hydrogen sulfide (interferent), carefully remove plug from vial adapter on back of sampler housing. Immediately screw open end of sorbent vial clockwise into adapter until secure (see inset 8A).
