HYBRID Trac Technology

High Performance Technology

Rapid analysis is crucial to modern process control. The ability to make even small changes quickly can add thousands of dollars to the bottom line over the course of a year, but accurate determinations are critical to making the right decision.

Unlike NIR or other technologies that only measure the surface of the sample, the HYBRID Trac utilizes direct moisture analysis and advanced NMR technology to analyze the entire sample. The result is an accurate analysis that is not dependent on sample uniformity and not affected by changes in color and texture.

Simple to Operate 

Only 3 samples are needed to create new methods. HYBRID Trac methods are robust, and need no calibration maintenance, as do NIR systems. Intuitive software makes it easy-to-use...no PhD needed. HYBRID Trac offers the perfect combination of speed and accuracy for fat and moisture analysis in both high- and low-moisture samples.

How does it work?

The HYBRID Trac starts by using either direct microwave drying (utilizing official AOAC methodology) for samples that are >12% moisture or advanced NMR technology for ≤12% moisture samples. For high moisture samples, the SMART Turbo System dries the sample using microwave energy. The SMART is the only system that incorporates the use of IntelliTemp™ Temperature Feedback to ensure rapid and complete drying without burning the sample. The SMART continually monitors both the temperature of the sample and its weight to give you the most accurate results, fast.

Once moisture content is known, the amount of fat is determined in only 8 seconds using Nuclear* Magnetic Resonance (NMR) technology. NMR is the same technique as Magnetic Resonance Imaging (MRI), which has been widely used in the medical profession for years to accurately image the human body. In addition, many industries quantify oils, fats and/or moisture with NMR.

The dry sample is introduced into the NMR which sends a pulse of radio-frequency energy through the sample, causing the hydrogen to generate a signal. The intensity of this signal can then be analyzed to determine the amount of fat protons present in the sample. Because fat protons decay more slowly than the other constituents in food (e.g. protein, carbohydrates), they can easily be directly measured. In addition, NMR measures fat protons throughout the entire sample and is not affected by surface characteristics (color, ice crystals, sample changes, etc.) which create problems for some techniques.

Low moisture samples are tested using CEM’s patent-pending Interference-Free Moisture Technology (IFM). Traditional NMR systems have problems accurately determining the bound moisture in dry products, as even a small percentage of fat in the sample can result in an incorrect reading. IFM overcomes this limitation and allows an accurate determination of both the moisture and the fat content of the sample. When coupled with QuikPrep, the patent-pending sample preparation technology, the results are fast and accurate.

*The word "nuclear" in the name of the technique refers to the instrument's ability to analyze the nuclei of the sample. NMR technology does not generate or use ionizing radiation.
