Introduction
The Photoacoustic Field Gas-Monitor INNOVA 1412 is a highly accurate, reliable and stable quantitative gas monitoring system. It uses a measurement system based on the photoacoustic infrared detection method, and is capable of measuring almost any gas that absorbs infrared light.
Gas selectivity is achieved through the use of optical filters. By installing up to five of these filters in the 1412, it can measure the concentration of up to five component gases and water vapor in any air sample. Although the detection limit is gas-dependent, it is typically in the ppb region. The accuracy of these measurements is ensured by the 1412s ability to compensate for temperature and pressure fluctuations, water vapor interference and interference from other gases known to be present. Reliability of measurement results is ensured by regular self tests, which the 1412 performs. By the nature of this measurement system, it requires no consumables and very little regular maintenance, for example, for most applications recalibration is only necessary one two times a year.
The monitoring system is easily operated through either of the two user interfaces: the front panel with its push buttons and display providing short explanatory texts, or the PC Software, with its graphical interface. Both interfaces enable the monitor to be set-up, a measurement sequence started and the resulting concentration values of the specified gases viewed while monitoring.
The monitor is equipped with two standard interfaces: IEEE-488 and RS-232 (optional JV 0901 converter RS-232 to USB. These enable the monitor to be integrated into automated process systems. The 1412 has a built-in pump system that allows samples to be drawn from up to 50 m away.
Selectivity
The gas selectivity of the 1412 is determined by the optical filters installed in its filter wheel. Because water is nearly always present in ambient air and absorbs infrared light at most wavelengths, it contributes to the total acoustic signal in the analyses cell. Therefore, the monitor is permanently fitted with a special filter, which measures water vapor and enables the 1412 to compensate for water vapors interference. By selecting different filters, this technique can also be used to cross-compensate for known interferent gases.
Uses
- Indoor Air Quality measurements
- Ventilation measurements using tracer gas
- Occupational Health and Safety measurements of possible production or accumulation of toxic/carcinogenic substances in working areas
- Monitoring of anaesthetic agents in hospitals
- Emission monitoring of greenhouse gases from agricultural production
- Emission monitoring of exhaust from chemical processes
Features
- Selectively measures a wide range of gases/vapors
- Linear response over a wide dynamic range
- High stability (low drift) makes calibration only necessary one two times a year
- Extremely reliable due to self-testing procedures
- User-friendly procedures for calibrating the monitor, presenting and analyzing measurement data via the PC user interface
- Accurate compensates for temperature and pressure fluctuations, water vapor interference and interference from other known gases
- Extremely low-volume flushing possible
- Operates immediately almost no warm-up time necessary
- Presents measurement data via connected PC both in tabular and graphic formats up to five gas concentration and water vapor graphs displayed, simultaneously
Calibration
After the relevant optical filters are installed, the monitor must be calibrated. This is achieved through easy-to-use menu-driven instructions. With its high stability, calibration of the 1412 is seldom necessary more than once a year.
Calibration is performed using either the PC Software or directly from the front panel.
Operation
The 1412 monitoring system is easy to operate using either the PC Software or the front panel push-keys (which can be locked and accessed at three levels using passwords). The monitor can be operated as both an on-line and off-line instrument. Using these user-interfaces with their logical division of information, everything that needs to be defined is achieved prior to starting the monitoring task.
Setting-up the Monitor
The Set-up option enables all the parameters necessary to complete the monitoring task to be defined. Within this option, the Sample Integration Times (S.I.T.) is set enabling measurement results to be weighted sensitivity versus speed.
Starting Measurements
Once the set-up parameters have been defined, measurements can be started either immediately or later using a delayed start time. Once started, the monitoring task then continues until it is stopped either manually or using a defined stop time.
Alarms
When measuring, two Alarm trigger levels, which provide high alarm limit one and two for each measured gas, can be defined. These can also be linked to audible alarms.
Measurement Results
On-line Measurements
Using one or more of the monitors standard interfaces, measurement results are transferred directly to a PC. Here they can be displayed on screen as real-time values in tables and graphs or integrated into the process system.
In the PC Software, the graphs can be set up to display only the desired gases, defined concentration ranges and results from statistical analyses. Also, when using the PC Software, all measurement data is stored in user-defined databases in an MS-Access format.
Off-line Measurements
Gas-measurement result data is displayed on the 1412s screen (Display Memory) as soon as it is available, and is constantly updated. During a task, the 1412 performs running statistical analyses of the measured gas concentrations, calculating a variety of values for each monitored gas.
This data in Display Memory can be copied to the Background Memory, which is a non-volatile storage area. Data stored in Background Memory can be recalled to Display Memory. From this memory, data can, if necessary, be uploaded to the PC Software and printed out in a list form on any standard text printer via the 1412s IEEE and RS-23 interfaces.
Reliability
Executive self test check: software, data integrity, and the 1412s components to ensure that they function properly. If a fault is found, it is reported in the measurement results, so that the integrity of the results can be ensured.
If the power supply fails, the 1412 will automatically start up again when power is restored. Measurement data stored in the monitors memory is not affected.
Maintenance
The only maintenance tasks necessary are calibration and changing the air filter. Both tasks are easily performed, and the frequency for changing the air filter depends on the individual applications.
Remote Control Options
LumaSense Technologies offers two additional application software programs, the Application Software INNOVA 7300 and the Application Software INNOVA 7620.
Using 7300, a computer can remotely control a 1412 together with one
Using the 7620, a computer can control a 1412 together with up to two
