A term used to describe the “air space” above/around the product in a package is head space.  Illinois Instruments manufactures a diverse line of Head Space Analyzers designed to measure this head space.

The head space in a package typically consists of ambient air.  However, when shelf life is critical, this head space is often replaced with a head space of nitrogen, carbon dioxide, or some combination thereof.  This is known as modified atmosphere packaging (MAP). The new head space gas must be analyzed to confirm that the head space gas concentrations are correct. Analyzing your package’s head space is the only way that you can be 100% sure that your head space gas mix is correct.  Illinois Instruments’ Head Space Analyzers offer a very affordable way to measure oxygen, carbon dioxide, or both in the head space. 

Illinois Instruments' model 6500 Oxygen Head Space Analyzer measures trace oxygen within packaging head space. The Model 6500 offers new levels of performance, technology and operator ease to fulfill the latest industry demands for accuracy and reliability.

This highly advanced instrument is equipped with an integral sampling systems, a unique miniature zirconia sensor, and microprocessor control to deliver the most accurate and repeatable performance possible.

One touch automated calibration and product analysis make these analyzers easy to use.

Rugged and compact epoxy clad cabinetry, seamless operator's console and no-compromise engineering place these instruments at home in both the laboratory or the demanding climate of the production floor.
 

Automated package sampling is easy. Just insert the sampling needle into the package and press analyze. The instrument does the rest: extracting the sample, analyzing sensor output and holding the results for viewing on the bright autoranging display.

Head space samples may be injected directly into the instrument when automated sampling is not practical.

Versatile accessory sampling system is perfect for rigid packaging and has proven rugged and reliable in hundreds of demanding application.
 
 

All 6000 Series Analyzers include these Special Features:

A.  Precision flowmeter provides visual confirmation of sample flow. Unlike warning lights, users can monitor system performance and resolve potential problems before they occur.

B.  Convenient wand holder is easy to use and helps prevent needle contamination and sample line damage.

C.  Display hold locks most recent high or low concentration value. Bright, large character display is easy to read in any lighting condition. Status lights indicate mode of operation.

D.  Auto calibration is simple. With a single button the instrument self calibrates in just 30 seconds using ambient air.

E.  Timed, automatic analysis is provided at the touch of a button. Programmable sampling duration and data integration make these among the most advanced head space analyzers available.

F.  RS232 output prints product description and sample data to 40 column printer for hard copy of calibration and test results. Prints test "Fail" according to user defined alarm settings.

G.  Unique sensors allow analysis of small sample volumes. Response is typically less than five seconds for oxygen and ten seconds for carbon dioxide. Internal microprocessor manages calibration, autoranging, pump speed and duration, time and date, outputs, and many other functions to ensure consistent, error-free results.

H.  Rugged sample wand is designed to accept standard luer accessories and includes easily replaced needles and particulate filters.

Compact enclosure maximizes space on carts and table tops. Seamless cover design and polycarbonate operator's panel sheds spills and resists most chemicals and solvents.

User friendly software parameters are easy to enter and can be secured against accidental change.
