The Advanced Spectra Search (ADSS) program comes standard with Advanced SearchNAV (ASN).
ADSS aids in the analysis of spectra for unknown samples. The program uses two functions to identify the sample: Classification and Search.
ADSS classifies the spectrum of an unknown sample into one of 35 different categories.
ADSS compares the spectrum of an unknown sample with spectra in standard libraries to determine the closest standard sample match.
Open a spectrum file for an unknown sample. Select the Classification check box and click Run. The Classification results are displayed in the Classification Hit List tab shown in the bottom of Figure 1. The unknown sample spectrum and the associated Classification category spectrum are shown at the top of Figure 1. The 35 Classification categories are displayed in Table 1.
Acetone | Acrylic resins | Alcohol |
Carbonates | Carboxylic acids | Carboxylic acid esters |
Carboxylic acid esters (oil) | Carboxylic acid salts | Cellulose and sugar |
Epoxy resins | Fluorides | Hydrocarbons |
Hydrocarbons (polyethylenes) | Hydrocarbons (polypropylenes) | Nitriles |
Phenolic resins | Phosphates | Polyamides |
Polycarbonates | Polyethers | Polyethers (polyacetal) |
Polyesters | Polimides | Polyvinyl acetates |
Polyvinyl alcohol | Polyvinyl chlorides | Proteins |
Silica | Silica (talc) | Silica (kaolin) |
Silicone | Sytrene | Sulfates |
Urethanes | Water |
JASCO provides several library files for the ADSS program as standard and offers an optional plastics library for purchase (Figure 2/Table 2).
The ADSS program can also import third-party libraries or custom user-buildable libraries created in the Spectra Library Manager program.
Food Additive | Foreign Materials by ATR | Foreign Materials |
Inorganic | Inorganic FIR | Organic |
Polymer | Plastics (Optional) |
Open a spectrum file for an unknown sample and select the Search check box. Click Library to select the libraries you would like to register for the Search. The Search results are displayed in the Hit List tab shown at the bottom of Figure 3. The unknown sample spectrum and the associated Search spectrum are shown at the top of Figure 3.
