SP-IR30A Double Beam Infrared spectrophotometer is an upgraded version of the National Pharmacopoeia SP-IR-30 dual-beam proportional recording infrared spectrophotometer.
Can record the infrared absorption spectrum and reflection spectrum of a substance at 4000-400cm-1.
Adopts a DTGS receiver and has reliable quality. , low maintenance cost.
Widely used in various fields such as pharmaceuticals, chemicals, petroleum, materials science, public security, health, environmental protection, etc.
This instrument occupies the main market of domestic infrared instruments and is an indispensable analytical and testing instrument for scientific research, production and teaching.
Features of SP-IR30A Double Beam Infrared spectrophotometer
- Proportion in the country for the first time using a computer recording principle
- High-energy double blazed grating covering the entire operating band
- Using computer for instrument control and data processing, to provide matching function, users can create their own map database
- WINDOW English operating system, a simple, easy to understand
- USB2.0 interface for data exproting
- TGS as a receiver using domestic substitute imports thermocouple, to ensure high performance and stability under the preliminary, low price, low maintenance costs.
Main functions of the software
- Audit tracking function: Encryption of data storage can be achieved through the database, and the original data can be recorded accurately and clearly simultaneously, and the original records cannot be modified manually. The record content includes: user login time, modification time, collection parameter content, etc. You can build your own map database.
- Data processing functions: spectral background baseline memory, spectral background baseline correction, spectral data accumulation operation, %T & ABS conversion, spectral data smoothing operation, spectral baseline tilt correction, spectral file management, spectral peak detection, designated peak labeling, Spectrum comparison, differential operation of spectral data, four arithmetic operations of spectral data, spectral scale expansion, spectral absorption expansion.
- Data export function: view the spectrum library, preview the spectrum, print the spectrum, export Excel data, etc. All the above functions can be operated offline.
