Trace Oxygen Analyzer for Modified Atmosphere Packaging

trace oxygen analyzer for MAP

The TecPen Oxygen Analyzer for Modified Atmosphere Packaging and the TecPen Oxygen and CO2 Headspace Analyzer both provide fast and accurate oxygen level measurements between 0.01 and 5% by volume. The Headspace analyzer includes the ability to measure 0.1-100% CO2.

How does the TecPen work?

A thin, hollow needle and micro-pump takes gas samples through clear packaging material. A pierceable septum is applied to the packaging material to insure outside air does not mix with the air inside.

This makes the TecPen useful as a gas analyzer for quality control during modified atmosphere packaging (MAP) testing shrink wrapped or vacuum sealed food products, or as a head space oxygen analyzer.

Because it is hand-held, rechargeable and contains a built-in micro pump, this portable oxygen analyzer can be used in the field for controlled atmosphere storage (CAS) applications like fruit transportation where < 5% oxygen levels must be maintained.

In addition to food, the TecPen can be used as a head space gas analyzer for quality control testing of safety sealed containers for pharmaceuticals, makeup, skin care products or in any application where oxygen can impact the safety, freshness or longevity of the product.

In the lab, the this trace oxygen analyzer can be useful in biochemical and molecular biology research as well as testing for pathogenic microorganism growth in sealed containers.

This video shows the TecPen in use.

Long-Life Optochemical Sensor

The TecPen’s speed and low-oxygen level measurement performance is due to its advanced opto-chemical sensor technology. The benefit of opto-chemical sensing is speed and accuracy. The TecPen’s sensor can respond to changes in oxygen levels in less than a quarter of a second. Depending on the length of the cannula and tubing the sensor can display the oxygen level in as little as 3 seconds. And because of the inherent accuracy of opto-chemical sensors, the TecPen can measure oxygen levels down to 0.01% or less than 4 parts per million.

Data Logging

modified atmosphere packaging testing

The TecPen features built-in data logging of time-stamped oxygen level measurements for quality control. Data can be downloaded as industry-standard .CSV files via the same USB cable that is used to recharge the built-in Li-Ion battery. This makes the TecPen useful for gathering data each day for over time for scientific applications or where data must be logged and stored for quality control.

Easy to Use

The TecPen comes pre-calibrated from the factory. It only requires two buttons to operate: power on, and start measurement. Each time a measurement is taken, the TecPen displays it in large characters on the LCD screen.
