    Machine condition monitoring for aviation, aerospace & airlines

    Overview

    Oil analysis has long been practiced for aircraft engines and other airborne oil-wetted systems such as hydraulic systems and gear boxes in helicopters. Military organizations are perhaps the number one users of oil analysis testing and commercial aviation also has a long history of oil analysis. A number of airlines throughout the world do their own oil analysis, but in many cases they send samples to commercial oil laboratories. Engine manufacturers also do oil analysis as part of engine development and testing.

  • Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the extraction of LpDNPH S10 cartridges and putting it in-line with the HPLC analysis will significantly reduce manual labor using this technique and this will improve reproducibility of the method by reducing potential experimental errors by the operator. The automation and unattended operation of the method leads to high throughput for determining airborne formaldehyde and acetaldehyde.
