Application Notes

Orchard and vegetable fruit crop
   maturity determination using handheld NIR
   analyzers.

Written by: Dr. F.G. Haibach

A five-second analysis of fruit ripeness is possible using the PHAZIR. The analyzer is fast and reliable enough to allow a minimally-trained user to profile an entire field.

   Rapid, non-destructive determination of Brix    on whole grapes on-cluster.

Written by: Dr. F.G. Haibach

Rapid assesment of Brix in the vineyard is critical in determining harvest timing. This analysis can be perfeormed through the skin of the skin of the grape without removing it from the cluster. In addition, the results of the analysis are archived for later analysis.

   Verifying Feed Ingredients On-Site with    FeedME and the PHAZIR

Written by: Dr. F. G. Haibach

Identification and qualification of incoming animal feed ingredients can be rapidly determined. Handheld analzyers significantly enhance workflow and productivity.

Determination of Moisture Content
   in Carbohydrates.

Written by: Dr. Suzanne Schreyer & Dr. F.G. Haibach

Moisture content determination is important for the processing of many powders. Powders have a large surface area and can absorb a large fraction of water by weight. The absorbed water changes the interactions between individual particles changing the way the powder processes. Water changes the flow, compaction and response to heat of the material. Hygroscopic materials, like sugar, starch and, to a lesser degree, cellulose can absorb relatively large quantities of water.

Determination of EthnanolIn Wine

Written by: Dr. Suzanne Schreyer

In the following discussion, a method is presented to determine the added ethanol content in a white wine. PLS models were developed based on spectra obtained using NIR instruments capable of being part of an at-line process. Two instruments were evaluated for their predictive ability by reporting the accuracy and repeatability of resulting PLS models.
