23rd April 2008 began, the Virginia list INTOX EC / IR II as an approved device in accordance with the provisions of breath alcohol testing. Virginia now has a contract with Intoximeter to 220 aircraft, signed the day.

Alka Lohmann is the director of the Virginia section of unlicensed alcohol. At the meeting of the 5th May 2008 Scientific Advisory Board, Ms Lohmann, a report on the state II EC / IR. She said that the 50 states, the tester is only used in four states outside of Virginia: West Virginia, Wisconsin, North Carolina and Tennessee. Mrs. Lohmann did not explain why only 10% of the States of the EC / IR II used. She said that the new tests offered advanced features for communication, increased problem solving form the laboratory and the ability to use a dry gas.

Mrs. Lohmann was asked about the types of reports that can be applied to the device. She said that the same reports are currently available for the new machine.

In analytical chemistry, the analysis of a substance to be confirmed by independent analysis and the analysis of alternatives. Agreement between the two different methods of analysis provides reliable results.

On behalf of the EC / IR II implies that the machine measure the alcohol content of the topic in two ways: CE stands for fuel cells or fuel during IR means infrared. By this method, the device guarantees the reliability of the results by using various tests. This would allow the internal substantive EC / IR II has a distinct advantage over the reliability of devices using a single technology.

Intoximeter Unfortunately, to coordinate the various methods of analysis. Because of this failure, the instrument is not two independent methods for measuring the concentration of alcohol. Instead, the EC / IR II uses only the fuel cell to measure alcohol and determine the alcohol content in blood. Infrared is used to monitor the quality of respiratory samples and to detect mouth alcohol.

The fuel cell component is not able to detect mouth alcohol. The fuel cell simply reports the total concentration of alcohol present with the registration of the presence of alcohol in the mouth.

to the passage of time and fuel changes are often calibrated in sensitivity to obtain the accuracy. IR detectors require no calibration weeks. Since the drift electrode microstructure changes over time in the sensor base. This drift takes Sych with the EC on the IR.

calibrate the device every few weeks would be very demanding and time consuming. Some states have solved this problem by disabling the IR completely. Once the IR detector is disabled, the device lacks the ability to detect mouth alcohol.
