What Hair Reveals
The detection of illegal drugs and pharmaceuticals plays a role in various fields, for example in forensic science, road traffic accidents, in competitive sports or at the workplace. Chemical substances can be detected in blood, saliva, urine and in hair. Hair has the great advantage of storing the substances for a long period, which means that detection is still possible several months after consumption of the drug. In addition to the detection of drugs, hair samples are also used for DNA analysis as well as for the analysis of heavy metals and minerals.

Efficient Grinding at –196 °C
RETSCH’s New CryoMill for Safe and Reproducible Grinding with Liquid Nitrogen
Preparation of Elastic Plastics for the Detection of PAH
Polycyclic aromatic hydrocarbons, short PAH, are usually a by-product of combustion and can be found, for example, in cigarette smoke or oil-based products. Mineral oil containing PAH is often used in rubber products as plasticizer, especially in black-coloured products such as car tyres, rubber grips of tools or rubber shoe soles. It was discovered that some polycyclic aromatic hydrocarbons are carcinogenic, so that maximum permissible values have been determined for the concentration of PAH in consumer products.
Size reduction of elastic plastics with volatile components
Neutral-to-analysis sample preparation for the detection of PAH and phthalates
Using the CryoMill for samples with volatile substances
For the size reduction of many materials it is more suitable to use a cryogenic mill than a laboratory mill which operates at room temperature. The sample is embrittled by liquid nitrogen which improves its breaking behavior when submitted to impact, pressure and friction; moreover, volatile components of the sample are preserved. The RETSCH CryoMill is not only the most modern and safest cryogenic mill in the market, it also provides excellent grinding results.
What hair reveals
The detection of illegal drugs and pharmaceuticals is important in areas such as forensic science, traffic or competitive sports. Chemical substances can be detected in blood, saliva, urine and hair, the latter having the advantage of storing the substances for a fairly long period, depending on the hair length. In addition to the tracing of drug abuse, hair samples are also used for DNA analysis.
Aufbereitung von PET Preforms zur nachfolgenden Analytik
In der Getränkeindustrie werden die Kunststoffflaschen auf das potentiell krebserregende Acetaldehyd geprüft. Dies erfolgt meist in den Vorstufen der Getränkeflaschen, den so genannten Preforms. Bevor der Nachweis erfolgen kann, muss das Acetaldehyd erst aus der Probe extrahiert werden. Um dies reproduzierbar zu ermöglichen, ist es notwendig, die Probe zunächst zu zerkleinern. Dabei ist zu beachten, dass Acetaldehyd eine sehr leicht flüchtige Substanz ist. Der während der Vermahlung notwendige mechanische Energieeintrag kann zur Erwärmung und damit zur Verdunstung des Acetaldehyds führen. Um diesen Effekt zu verhindern, ist die Kryogenvermahlung die ideale Methode.
Vermahlungen ohne Verlust von Inhaltsstoffen
Kryomühle im Einsatz an der BTU Cottbus
Bei vielen Materialien ist es vorteilhaft eine Kryomühle für die Zerkleinerung einzusetzen, statt einer Labormühle, die bei Raumtemperatur arbeitet. Die Probe wird durch den eingesetzten flüssigen Stickstoff versprödet und kann darum besser durch Schlag, Druck und Reibung zerkleinert werden; außerdem bleiben leicht flüchtige Bestandteile erhalten. An der Brandenburgischen Technischen Universität (BTU) Cottbus ist eine Kryomühle in den Bereichen Kunststoffrecycling und Biomaterialien im Einsatz.

Ensayos en “preformas” de PET para seguridad del consumidor
El formaldehído es un producto químico utilizado ampliamente en la producción industrial de materiales como plásticos, en el procesado de telas o en la preservación de materiales biológicos. Sin embargo, el formaldehído es también considerado por muchas normas como peligroso para la salud. Puede provocar reacciones alérgicas y ha sido clasificado como cancerígeno en 2004. Según la norma alemana Oeko-Tex 100, la ropa para niños no debe contener concentraciones de esa sustancia superiores a 20 PPM.
