Occupational hygiene monitoring

of formaldehyde and other

industrial chemicals

Thorough expertise in occupational hygiene monitoring.

Covers the whole range of substances relevant for resin production using state of the art

monitoring techniques.

Quality verified through annual participation in international Round Robin tests organized by

Institut für Arbeitschutz der Deutschen Gesetzlichen Unfallversicherung.



Occupational hygiene monitoring of formaldehyde using 2,4-DNPH

Principle

The procedure utilizes sampling cartridges containing silica gel coated

with 2,4-dinitrophenylhydrazine (2,4-DNPH). When air is sucked

through the cartridge using a calibrated precision air sampling pump,

formaldehyde reacts with the 2,4-DNPH to the corresponding

formaldehyde-2,4-dinitrophenylhydrazone. This hydrazone is easily

analyzed using high performance liquid chromatography (HPLC).

The 2,4-DNPH procedure is the state-of-the-art procedure for

monitoring formaldehyde in air.

Limit of quantification

Short term (15 min / 2,5 L air): 0,05 ppm

Long term (8 hours / 60 L air): 0,002 ppm

Note

This procedure also applies to other aldehydes and ketones.



Occupational hygiene monitoring of phenol

Principle

The procedure utilizes sampling tubes containing XAD-7 adsorbent.

XAD-7 is an organic polymer. When air is sucked through the sample

tube using a calibrated precision air sampling pump, phenol is

adsorbed to the surface. During analysis phenol is extracted from the

adsorbent and analyzed using high performance liquid

chromatography.



Occupational hygiene monitoring of volatile organic compounds

Principle

The procedure utilizes sampling tubes containing a charcoal

adsorbent. When air is sucked through the sampling tube using a

calibrated precision air sampling pump, organic compounds are

adsorbed to the surface. During analysis the compounds are

extracted from the adsorbent and analyzed using capillary gas

chromatography.



Occupational hygiene monitoring of methanol and ethanol

Principle

The procedure utilizes sampling tubes containing a silica

adsorbent. When air is sucked through the sampling tube using

a calibrated precision air sampling pump, the alcohols are

adsorbed to the surface. During analysis the alcohols are

extracted from the adsorbent and analyzed using gas

chromatography.



Occupational hygiene monitoring of dust

Principle

The procedure utilizes sampling cartridges with pre-weighted

filters. When air is sucked through the sampling cartridge using

a calibrated precision air sampling pump, airborne dust is

collected on the filter. During analysis the filter is weighed and

the air concentration of dust calculated.



Occupational hygiene monitoring of isocyanates

Principle

The procedure utilizes sampling on filters impregnated with

1,2-methoxyphenyl piperazine according to MDHS 25/3. When

air is sucked through the filter cartridge using a calibrated

precision air sampling pump, the isocyanates are adsorbed to

the filter. During analysis the isocyanates are desorbed from

the filter and analyzed using high performance liquid

chromatography.



Stack emission monitoring

Highly sophisticated procedure for online monitoring, using miniaturized capillary gas

chromatography.
