The asphalt four-component analyzer is used to analyze the chemical composition of road petroleum asphalt. It evaluates the compositional characteristics and performance changes of asphalt through solvent precipitation and chromatographic column separation methods. It is widely used in laboratory research, quality control and material performance evaluation.

Asphalt Four-Component Analyzer(SARA Analysis)

Model:TDSF-4

I.Product Introduction

This instrument is designed and manufactured in accordance with the requirements of T 0618-1993"Asphalt Chemical Component Test(Four-Component Method)"in the People's Republic of China industry standard JTG E20-2011"Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering".It uses solvent precipitation and chromatographic column separation to analyze the four components of road petroleum asphalt.Meanwhile,the instrument's test principles and methods refer to ASTM D4124,"Standard Test Method for Separation of Asphalt into Four Fractions".

This instrument consists of an asphalt extractor(comprising a spherical condenser and a 100ml extractor assembly)and a glass adsorption column.Its structure and technical parameters fully comply with the requirements of the T 0618-1993 standard.Equipped with a dedicated floor clamping device,it is easy to assemble into a test mechanism,making it very convenient for users.
