Scan-n-Search Overview:
- A complete program for handling Infrared data
- A free viewer for infrared data
- A free search program for FDM IR Reference Spectra Databases
- Very easy to use, makes complex data manipulations simple
- Powerful Batch-Processing automates repetitive tasks
- Scaleable from the teaching lab to the on-line process environment
- Extensible using the powerful open-source Python programming language
- Reads and writes data in industry-standard file formats
- Collects data directly from the M530 IR spectrophotometer
Software Capabilities:
Step 1: In the M500/M530 start up screen, it checks your computer and network for all available drives so you can open and share to them.
Step 2: In the Scan-n-Search is the polished instrument user interface that makes data collection a breeze. The single beam background scan is displayed and stored as the background for the sample runs to come.
Step 3: In the Instrument Control Section, once the background Scan has been done, change to Sample mode and collect a real time %T scan of your sample. If you like the finished scan you can choose to save it, print it or do other advance manipulations on it.
Step 4: Manual Peak Labeling at a click.
Step 5: Advanced Functions Savitsky-Golay Smoothing for reduce system noise.
Step 6: Advanced Functions - Library Search - Your Spectrum can be searched / compared against premade and libraries you construct.
IR Reference Spectra Databases
An infrared spectrum of a molecule is like a fingerprint. By comparing the spectrum of an unknown compound to a library of data, the spectroscopist can identify the unknown. This technique has wide applications in many fields such as forensics, environmental chemistry, research, industrial quality control, and teaching.
Scan-n-Search Infrared Software includes a complete spectral library search tool with user-defined region searching, many search algorithms, and customizable reports.
Commercially available Reference Spectra Databases (Libraries)
Hundreds of Thousands of reference spectra are available from:
When ordering STJapan or NICODOM databases, specify the format to be "Galactic - Grams/32 & SpectralID".
Scan-n-Search Infrared Software can search any database from any source that is in "Galactic - Grams/32 & SpectralID" format.
Scan-n-Search Infrared Software can search WinFIRST libraries and Sadtler User Libraries, and can search against folders of individual files.
