THE OIL STABILITY INDEX

Definition: All oils and fats have a resistance to oxidation which depends on the degree of saturation, natural or added antioxidants, prooxidants or prior abuse. Oxidation is slow until this resistance is overcome, at which point oxidation accelerates and becomes very rapid. The length of time before this rapid acceleration of oxidation is the measure of the resistance to oxidation and is commonly referred to as the induction period, or Oxidative Stability Index.

The Omnion Oxidative Stability Instruments provide an instrumental determination of the oxidative stability of fats oils and other organic materi-als, eliminating the time, inconvenience, hazards and errors associated with manual titrations. Continuous data monitoring (up to 24 channels simultaneously) ensures no missed endpoints.

Shelf Life/Predictive ValueThe Omnion OSI accelerates the development of oxidative rancidity so that the useful life of an oil containing material may be determined. Unlike tests such as peroxide value, which determine oil quality only at the time of the test, the OSI has predictive value, therby allowing quality decisions to be made before spoilage becomes a problem.

The OSI is an invaluable quality control tool for eliminating inferor ingredients, for isolating process variables causing stability problems, for measur-ing the stability of finished products, for evaluating antioxidant activity, for monitoring the deterioration of cooking oils with use, for determining the stability of PVC, and for many other applications where oxidative rancidity is the cause of product failure. Because the OSI has predictive value, problems are detected and eliminated before they cause rejection, unlike other tests which merely indicate that problems have occurred after it is too late to correct them.

Designed for precision and accuracy, ease of use and maintenance, and inexpensive operation, the OSI is used worldwide by refineries, food compa-nies, pharmaceutical concerns, research institutes, chemical firms, pet food manufacturers, universities and governments agencies.

THE OSI ADVANTAGEEASY TO USE | SIMPLE TO MAINTAIN | NO MOVING PARTS | NO CHEMICALS | UNBREAKABLE SENSORS

Excellent precision

Continuous data monitoring ensures no missed endpoints

Automatically calculates induction times and plots conductivity/time curves

Maximum sample throughput Load new samples or remove analyzed samples without affecting runs in progress

Temperature selection and operation OSI-24: two temperatures between 40-220 C OSI-6: any temperature between 40-220 C

Sample cells are test tubes which are inexpensive. They are often considered disposable, eliminating expensive and time consuming cleaning procedures

Conductivity cells are inexpensive test tubes

Rugged, unbreakable, chemically inert sensors provide long life and stable cell constants

Excellent temperature control
