Description
Liquid Paraffin (Mineral Oil, CAS 8042-47-5) is widely used in analytical laboratories as an inert, low-reactivity medium for sample preparation, particularly in infrared (IR) spectroscopy workflows. In solid sample analysis, researchers often face challenges in achieving uniform dispersion without introducing strong background absorption signals. Liquid paraffin addresses this limitation by acting as a stable mull medium that allows fine grinding and dispersion of solid samples for IR spectral acquisition.
In IR spectroscopy applications, inconsistent sample preparation can lead to distorted peaks, poor baseline quality, and unreliable interpretation. This laboratory-grade mineral oil provides a chemically stable, colorless, and non-volatile medium that minimizes spectral interference while maintaining sample integrity during analysis. It is commonly used in mull technique preparation where solid powders are dispersed in oil and pressed between IR plates for measurement.
Beyond spectroscopy, liquid paraffin is also used in general laboratory workflows requiring chemically inert oil phases, including surface protection, calibration procedures, and controlled environment testing where low chemical reactivity is essential.

Frequently Asked Questions
What is liquid paraffin used for in IR spectroscopy?
Liquid paraffin is used as a mull medium in IR spectroscopy to disperse solid samples evenly, reducing scattering and improving spectral quality. It provides a relatively inert background with minimal interference in key IR regions.
What is the role of mineral oil in sample preparation?
Mineral oil acts as a non-reactive dispersion medium that allows fine grinding of solid samples into a homogeneous paste for consistent IR analysis.
Is this product suitable for analytical-grade laboratory use?
Yes. This liquid paraffin is designed for laboratory research use, including spectroscopy and analytical chemistry workflows requiring stable and inert media.
Does mineral oil interfere with IR spectroscopy results?
Mineral oil exhibits relatively simple IR absorption features, making it suitable for many spectroscopy applications, although users should account for known background bands during analysis.
