The laboratory asphalt four-component analyzer is designed for the precise analysis of the chemical composition of asphalt binders. It enables detailed evaluation of the composition and performance characteristics of asphalt. This instrument is widely used in laboratory research, quality control, and asphalt material characterization.

Laboratory Asphalt Four-Component Analyzer

Model:TDSF-1

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.
