Product description
SP-IR30A is an upgraded double-beam infrared spectrometer based on the SP-IR-30 proportional recording design required by national pharmacopeia standards. It records absorption and reflection spectra over the 4000–400 cm-1 range and uses a DTGS detector to provide stable operation with low maintenance requirements. The instrument is intended for laboratory analysis in quality control, research and teaching.

Features

• Proportional recording with computer-based data acquisition for accurate spectral capture
• High-efficiency double-blazed grating covering the full operating range
• PC control and integrated data processing allowing creation and management of a custom spectral library
• Windows operating system with English interface for straightforward operation
• USB2.0 interface for data export and peripheral connectivity
• DTGS detector with domestic thermocouple solution for stable performance and reduced maintenance costs

Main functions of the software

• Audit trail: secure database storage with immutable original records; logs include user login, modification timestamps and acquisition parameters
• Data processing: baseline memory and correction, spectral accumulation, %T ↔ ABS conversion, smoothing, baseline tilt correction, peak detection and labeling, spectrum comparison, differential and arithmetic operations, spectral expansion (scale and absorption)
• Data export and reporting: preview, print and export spectra and numerical data to Excel; most functions available offline
