Pyrolysis System AOC-6000 Plus Multifunctional Autosampler System

High molecular compounds are subjected to pyrolysis at temperatures This is compatible with three sample introduction methods: liquid
of 500 °C or higher, and the obtained pyrolytic products are analyzed injection, HS (headspace) injection, and SPME (solid-phase
with GC and GC-MS. These pyrolytic products reflect the structure of microextraction) injection. It can be controlled with GCMSsolution
the original high molecular compounds. Accordingly, they enable the software.

Search software utilizing a pyrolysis library assists in the identification. analysis, can also be used. Automatic syringe replacement (10 µL to
1000 µL) and a stirring function enable sample dilution, the
automatic addition of internal standard substances, and the
automatic creation of calibration curve samples.

Py-Screener Phthalate Ester Screening System
™
The use of phthalate esters is restricted in toys and food packaging,
and they are expected to be classified as restricted substances in the
RoHS(II) directives. This system is simple to operate, even for novices. GC/MS Off-Flavor Analyzer
It consists of special software to support a series of procedures from Information Registered in Database
sample preparation to data acquisition, data analysis and
maintenance, as well as special standard samples and a sampling
toolkit.
Sample Preparation Does Not Require Organic Solvents Primary odor components GC/MS analytical conditions Sensory information of odor components
• Retention time information
• Odor characteristics
Standard samples and test samples can be prepared without using organic solvents. • MS and calibration curve information • Odor threshold value

This system combines GC-MS with a database of major odor-causing
substances and sensory information (types of smells and odor
thresholds). It provides the total solution required for off-flavor analysis.
Standard Samples Containing This product was developed in cooperation with Daiwa Can Company.
