Nomacorc Develops New Oxygen Measurement Device for the Bottling Line - NomaSense O2 Prime

Date: 05/26/10

Nomacorc is set to unveil a new oxygen sensor device developed to measure oxygen in the bottle. This tool will allow winemakers to accurately measure oxygen content in the wine as well as in the headspace (which eventually will get into the wine).

To be called NomaSense O2 Prime, this devise can measure oxygen in the bottle by reading levels of oxygen from small sensor dots attached to random bottles along a bottling line. The goal would be to place the sensors at a filled shoulder or even lower down on the bottle and in the “empty” head space, to measure both dissolved oxygen in the wine and potential oxygen that could later get into the wine. These sensor dots are activated by a blue light and transmitted through a fiber optic wand. The sensor dot responds by emitting a red light, which indicates the relative presence of dissolved oxygen in the wine. The analyzer translates the strength of the red light to a specific oxygen concentration level.

This devise is similar to the recently released NomaSense O2 Trace which provides rapid readings of trace amounts of oxygen up to 50 ppm and as low as 1 ppb and has applicability as a tool for controlling quality at every aspect of the winemaking process, from the amount of oxygen in the fermentation tank, through to microx, barrel-aging, and bottling.

The newly modified NomaSense O2 Prime, which does not have the low-limit detection of the O2 Trace machine, is designed with a measuring range suited for bottling applications only. The company said its easy-to-read display provides a fast and accurate reading of how much oxygen is captured in the dissolved and gaseous states of the bottling process and allows a producer to make sure there is an appropriate and consistent amount of oxygen ingress in each bottle.

The price for this Trace machine will be around 7,500 Euros (about $9,300); this smaller unit’s measurement device cannot read levels as low as the Trace machine’s capacity, so it would not be applicable at other points of production where oxygen values could be smaller.
