VITROCELL® Photometer 2.0

Online measurement of particle concentrations

VITROCELL® Photometer

VITROCELL® Photometers were specifically designed and developed to enable online measurements of particle concentrations at the inlets and/or outlets of the aerosol exposure top.

They are capable of measuring inline at very low flow-rates (e. g. 5 ml/min.) without any particle losses. The photometer measures a mere 62 mm in diameter. The photometers can be supplied with a control box and PC software for convenient read-outs.

Photometer Control Box and Software

The photometers are supplied with a control box for 4 Photometers and the VITROCELL® Monitor Software for convenient read-outs. The software features an area-under-curve function for easy determination of the total particle exposure. A calibration factor function enables a mass calculation per time units.

Monitor Software

The VITROCELL® Monitor software is capable to record 5 different parameters:

Deposition on the VITROCELL® QCM
Concentration of Aerosols measured by the VITROCELL® Photometer
Carbon monoxide concentration
Temperature
Humidity

VITROCELL® Photometer-Software Dual Screen

The software supports multiscreen use. By undocking charts from the main window they can be placed free in size and position or on a second screen.

GLP Edition

VITROCELL® Photometer-Software Good Laboratory Practice

VITROCELL® Monitor software GLP Edition was developed for laboratories operating under GLP conditions. This software upgrade assures tracability to high standards.

Example Application – VC 1 Smoking Machine

The Photometer can be connected to a VC 1 Smoking Machine. It is monitoring the aerosol concentration puff-by-puff. TPM for chemical analysis is collected on a 44 mm Cambridge filter pad.
