All GRIMM Instruments are Spectrometer, so each:

Gives all the PM`s at the same time

Or the Mass distribution

Or the Size distribution

Or the SVC differentiation

And Gravimetric correlation

all this is based on the atmospheric aerosol composition

Air Pollution/ Typical Sources



65

Why Semi-Volatile-Compounds Monitoring?

1. SVC`s have a significant contribution to mass

concentrations.

2. The health effect of SVC`s substances is probably

different from the health effect of non volatile solid

particles.

3. The use of DPFs reduces the emissions of soot

particles, but increases the concentration of precursor

gases for semi-volatile particles.

Therefore, it is necessary to make a quantitative

measurement of SVC.

GRIMM EDM-180/365 SVC

The EDM 180/365-SVC uses a heated

and one not heated sample pipe.

This concept works with

• TSP, PM10, PM2.5, PM1.0 and

• and also for particle sizing

The Temperature of the heated pipe is selectable

from ambient to 300°C.

In addition the dehumification system with the

Nafion dryer is used as well

A timed valve switches between the two sampling

pips

The difference are the SVC`s
