The Agilent Technologies Simulated Distillation (SIMDIS) Analyzer is a high-precision instrument designed to analyze complex hydrocarbon mixtures' detailed boiling point distribution. It operates within a temperature range of ambient to 450°C, enabling the analysis of various petroleum fractions, from light gases to heavy residues. The analyzer provides exceptional repeatability and accuracy, with a typical reproducibility of less than 1% for boiling point determination. It utilizes high-resolution capillary columns and precise temperature control, achieving a temperature stability of ±0.1°C, ensuring consistent results. The system includes advanced software that automates analysis, offering user-friendly data processing and reporting capabilities. The SIMDIS Analyzer supports compliance with ASTM methods such as D2887, D6352, and D7169, ensuring it meets industry standards for simulated distillation analysis. With a rapid analysis time of approximately 15 to 30 minutes per sample, this analyzer significantly enhances laboratory throughput and efficiency.
