برنامج BUCK Scientific Scan-n-Search بالأشعة تحت الحمراء مع الضمان

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:

• Fiveash Data Management. To find out more about FDM Databases and download a 14 day trial of four libraries visit www.fdmspectra.com.
• STJapan: www.stjapan-usa.com
• NICODOM: www.ir-spectra.com

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.

• Match spectra: set a group of spectra to have the same starting and ending values and number of data points

Synthesize Data

• Average / Add / Add with weights lists of individual datafiles to create new data
• Interactively add peaks to data by stretching data points

• Change header fields for corrupted or incorrectly converted files

Data Analysis

• Compute integrated areas of spectral regions
• Peak Picking automatically tabulates the peaks in a spectrum
• Manual Peak Picking and Labeling by right-clicking on a peak
• Peak Measurement: computes peak height using user-supplied peak endpoints
• Signal-to-Noise: computes signal-to-noise ratio over user-defined limits
• User Library Search: search unknown spectra against libraries of data.
