Overview

The GL-7100 infrared spectrophotometer is a specialized infrared spectrometer developed and manufactured according to the People's Republic of China Environmental Protection Standard "HJ637-2018" "Determination of Petroleum and Animal and Vegetable Oils by Infrared Spectrophotometry". It is used to determine the total oil, petroleum, and animal and vegetable oil content in water.

Features

First, the light is dispersed, then absorbed, which meets the requirements of infrared spectroscopy.
High-throughput optical system with integrated optical path design, short optical path, high energy, and small instrument size.
The use of an electrically modulated light source reduces the heat intensity of the light source, thus facilitating system heat dissipation.
A special precision stepper motor controls the grating, which has wavelength correction function, high wavelength accuracy, and good repeatability.
No manual zero-point adjustment is required; the software controls the zero-point to adjust automatically in real time (without baseline drift).
The sensor employs a low-noise amplifier circuit, which improves the instrument's signal-to-noise ratio and minimum detection limit.
Wide range of cuvette designs, suitable for any cuvette from 0.5 to 5 cm.
It has a continuous spectrum scanning function, scanning the entire infrared spectrum. Wavelength scanning speed: full spectrum scanning 3200nm～3600nm, 35 seconds/sample.
During sample measurement, the real-time scanned sample spectrum can be magnified arbitrarily from 0.5 to 40 times, facilitating the identification of interfering substances.
With the accompanying PC software, measurement data and spectra can be saved to the hard drive for easy access and printing at any time.
The instrument can be manually positioned to accurately measure absorbance at three wavenumbers: 2930 cm⁻¹, 2960 cm⁻¹, and 3030 cm⁻¹.
The oil analyzer software is powerful, capable of directly reading oil in water, oil fumes and mists in stationary pollution source exhaust gases, and petroleum hydrocarbons in soil. No manual conversion is required; a test report is automatically generated upon measurement completion. The report includes sample measurement data, sample scanning spectrum, standard curve equation and spectrum, sample setting conditions, customer information, etc. All data and spectra do not require computer screenshots for saving, meeting customer requirements.
