Spectrolytic was founded with the aim of making spectroscopy solutions available to the masses and to broaden the view of usability. Spectrolytic GmbH is a developer and supplier of infrared spectrometers and related solutions for a wide range of applications and markets. It also provides development and manufacturing services to third parties for both systems and solutions. Spectrolytic GmbH has its registered office in Wernberg-Köblitz, Germany, and its operating HQ in Wackersdorf, Germany. The Companies design, manufacture (internally and/or externally) a range of spectroscopy systems for a number of market sectors including but not limited to industrial and consumer applications. The Company also provide technology consulting, system design and development services, plus related manufacturing to customers on a contract basis. We believe we have some of the greatest minds in our business and will utilize this capability to expand our business to the benefits of the team and all stakeholders.

Milk analysis

3. 3
• Milk analysis is becoming more important for efficiency and herd management reasons.
• Being able to measure, in real time, key parameters of the milk can be used to optimise
feeding, detect illnesses and improve overall performance.
• Milk adulteration is also a growing problem worldwide where previously good milk is
contaminated with additives.
• In 2008 a Chinese milk manufacturer was charged for adding Melamine which falsely elevates
the protein contents in infant powder milk, as a result 13,000 babies were taken ill for kidney
inflammation and bladder carcinoma.
• Spectrolytic provides a compact and accurate solution for real time milk analysis application
based on analysing the mid-infrared absorption spectrum of a milk sample.
Introduction

What is mid-infrared spectroscopy
• A broad band emitter shines light through a samples
• The molecules in the sample will absorb certain wavelength of the light whist others pass through the
sample
• The wavelength of the light that is absorbed by the sample can be linked to certain molecular
structures that unequivocally identifies the molecules.
• Typically light in the wavelength range from 2.000nm to 12.000nm (mid infrared wavelength region)
provides the highest absorption signal whiles still providing a unique molecular identifier
• Monitoring the changes in the absorption spectrum of a sample over time provides information about
the concentration of relevant molecules in the sample.

-Light is emitted from broad band source
-Light penetrates cuvette with sample fluid/gas
-Certain wavelength get absorbed by sample
-Light is separated into its spectral components by
Linear Variable Filter (LVF)
-Signals (as function of wavelength) are detected with sensor
-Light is emitted from broad band source
-Light is coupled into an ATR crystal
-Sample fluid is placed on top of ATR crystal
-Light bounces in a controlled way through ATR crystal
and interacts with the sample on its surface
-Certain wavelength get absorbed by sample
-Light is separated into its spectral components by
Linear Variable Filter (LVF)
-Signals (as function of wavelength) are detected with sensor
