1. Introduction

Welcome and thank you very much for choosing our QUANTOFIX ® Relax analy-
sis.
The QUANTOFIX Relax is a reflexion photometer for the analysis of
®
QUANTOFIX ® test strips from MACHEREY-NAGEL.
The measurements are carried out under standardized conditions. Results may
be displayed, printed and sent to a computer. Instrumental evaluation eliminates
potential sources of error inherent to visual evaluation. Results will not vary
due to subjective color perception or different light sources. Additionally, errors
resulting from manual result administration are avoided. Featuring a clear touch
screen and intuitive user guidance, the QUANTOFIX ® Relax is ideal for quick,
efficient and comfortable work.

1.1 Technical description

The test strips is placed on a measuring slide with inbuilt reference pad, which
is moved into the instrument along a fixed measurement head. While moving in
and out of the instrument, the test strip is measured reflectometrically.
A pre-defined light source illuminates the test pad. A detection unit then mea-
sures the intensity of the reflected light at three different wavelengths. From this
information, remission values are calculated. The timing of the measurements
may vary depending on test strip and parameter. Using the remission values, the
instrument can – in contrast to visual evaluation - show continuous values within
the respective tests' measuring range. Once the result has been determined, it
is displayed on the screen, printed and sent to the instrument's interface.
