The HERACLES II Electronic Nose from Alpha MOS is the most powerful and flexible electronic nose yet. The system uses ultra fast gas chromatography technology with integrated pre-concentration.
It can analyze both the olfactory fingerprint of a product as well as the chemical compounds contributing to olfactory differences.
The HERACLES II system combines unique features:
Liquid and headspace injection modes
Two different metal capillary columns in parallel
Integrated solid adsorbent cooled trap
Aroma profiling and characterization correlated to sensory analysis
Chemical compounds separation, identification and quantification following GC accepted principles xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Conformity and Quality Control
Batch to Batch Consistency Testing
Process Optimization / Monitoring
Shelf-life and Stability Follow-up
Candidate Formulations Screening
Correlation with Sensory Panel Analysis
Fast analysis without compromise on resolution
Analysis time for VOCs < 20 sec., for SVOCs < 60 sec
High Sensitivity (ppm range)
Excellent repeatability of 1 to 3% in quantitative determinations and repeatability of 0.1 to 0.3% in retention times
Powerful and user-friendly software
Unique and easy to use functionalities such as the multivariate statistical package and multiple graphical tools xxxxxxxxxxxxxxxxxxx
Customizable and Comprehensive data processing including chromatography functionalities and fingerprint charts (Radar plot, SQC, PCA, DFA, PLS, SIMCA) xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Optional AroChemBase: chemical and sensory characterization of odour compounds
With this database containing chemical and sensory data, the molecules detected by the HERACLES system can be classified according to their Kovats indices:
More than 44,200 compounds, including 1,900 with sensory information
Possible selection by application or chemical family
NIST database included
Alpha MOS has developed an Electronic Nose (E-Nose) instrument to automate the analysis of odours and volatile compounds (VOC). In a way similar to the human nose, the Electronic Nose (E-Nose) allows global analysis of the headspace (volatile compounds) generated by liquid, gaseous or solid samples.
This odour analyzer consists of three main parts: a sampling system, a detection system and a data acquisition & processing system. Various sampling modes are available.
