AC Analytical Controls®, the global SIMDIS market leader, provides a full range of solutions that accurately determine true boiling point data from naphtha up to crude oil samples.

The IRIS 3.0 Client/Server seamlessly integrates SimDis & DHA XLNC into your networked CDS environment.

Boiling point data is a major specification in characterizing petroleum streams. PAC provides complete, turn-key gas chromatographic solutions for accurate determination of true boiling point data – from naphtha up to crude oil samples. By completely automating every step in the analysis, AC SIMDIS applications provide fast and accurate boiling point results.

PAC adds unique value to the industry by offering a 100% guaranteed solution, delivered fully factory calibrated, tested to certified reference materials, fine-tuned fully dedicated to methods specified by the user. PAC qualified service engineers commission the instrument and provide operator/user training.
