1Asphalt spectrometerInstrument Introduction

Generally speaking, the chemical composition of asphalt can be separated into four components: saturates, aromatics, resin, and asphaltene. The properties of asphalt will vary depending on the content of each component. By using a Fourier transform infrared spectrometer, rapid classification of asphalt can be achieved through testing and comparing infrared spectra.Infrared spectroscopy analysis is an important means of organic structure identification, especially the identification of functional groups in SBS. It allows asphalt to be compared and analyzed with asphalt samples in the database through the infrared spectroscopy asphalt rapid detection system, thereby accurately determining the authenticity of asphalt.

Each brand and model of asphalt has its own unique fingerprint spectrum, which determines the brand, model, batch, and place of origin through spectrum comparison; By analyzing the characteristic absorption peaks of the fingerprint spectrum, additives such as SBS and SBR, adulterated substances, and aging degree can be determined.This device is from our factoryA highly cost-effective Fourier transform infrared spectrometer that has been carefully independently developed. It has the characteristics of easy installation, simple use, and easy maintenance,broadUsed for qualitative and quantitative analysis of organic compounds, inorganic compounds, polymers, etc., with strong expansion function, it can connect diffuse reflection, ATR attenuated total reflection, non-contact external reflection, etc., with excellent performance.
