INTRODUCTION The Hetek Ethane Identifier, Model EI-5, is a portable, highly sensitive battery operated combustible gas analyzer designed specifically to detect the presence of Ethane in Natural Gas by elution (separation). The Ethane Identifier is a supplementary instrument, used primarily when it is necessary to determine in the field, whether or not a particular combustible indication is the result of escaping utility natural gas or a conflict gas such as naturally occurring methane.
PRINCIPLE OF OPERATION When the presence of a combustible gas or vapor has been established with a C.G.I., use the Ethane Identifier with the internal pump to draw a sample into the instrument. The valve should be in the “Sample” position. No display indication will occur as the sample is being drawn into the instrument. As the sample is drawn into the instrument, a portion of the sample is trapped inside the instrument in the short sample loop.
the equilibrium condition in clean air. Any substance foreign to clean air disturbs this balance, changing the ion flow in the conductance band of the semi-conductor detects the low concentration and early presence of foreign gases (methane, ethane, propane) rather than giving a quantitative measure of their concentration.
INSTRUMENT SPECIFICATIONS Instrument Weight: 1.3 lbs (0.59 kg) Carrying Case Weight: 7.3 lbs (3.3 kg) Includes Hydrocarbon Filter and accessories. Instrument Dimensions (LxWxH): 8.25 x 4.0 x 1.25 in (21 x 10 x 3 cm) Carry Case Dimensions (LxWxH): 17.5 x 13.5 x 4.
STANDARD KIT COMPONENTS Carrying case with foam 13” Lexan probe Hydrocarbon filter 3’ Sample hose Downloading software on a CD USB cable The Ethane Identifier has a built in data recorder that can be used to achieve either paper or electronic files for record retention. The data logger records the value, date and time stamp at one second intervals.
OPERATING INSTRUCTIONS Basic Ethane Identifier Procedure used in a clean background atmosphere: 1. Switch valve to the “Time” position. 2. Turn on the instrument using the on/off, zeroing switch on the left hand side of the instrument. 3. Let the instrument warm up for a few minutes. This is indicated by the graph on the display decreasing towards zero. 4. Zero the instrument using the zero potentiometer on the left side of instrument. 5.
3. Turn on the instrument using the on/off, zeroing switch on the left hand side of the instrument. 4. Let the instrument warm up for a few minutes. This is indicated by the graph on the display decreasing towards zero. 5. Zero the instrument using the zero potentiometer on the left side of instrument. 6. Connect the tubing with the hydrophobic filter in-line to the probe and the other end to the instrument port labeled Inlet. 7.
DATA LOGGING USE This data logger will store a reading, date and time, every second. The logger will store 64,000 readings before rewriting over the old information. A USB port on the end of the instrument and the included software will give the user the ability to down load the logged information. This will eliminate the need for an external chart recorder. 1. Install software on a computer according to the quick start guide. 2. Connect the instrument via USB to the computer and open the software. 3.
Note: Please do not adjust the voltage and time interval for the data logger as this will result in inaccurate logged readings. 5. Disconnect USB cable and proceed with one of the tests procedures outlined above. 6. When sample testing is finished, connect the Ethane Identifier to the computer and start the Easylog software. 7. Double click “Stop the USB data logger and download data” 8. Give the file a name and click save.
9. Click “OK” and the data will download and a graph will open automatically. 10. The graph can be exported to Excel along with all the readings in table form.
INTERPRETING READINGS Caution: For accurate indications the temperature and humidity of the atmosphere being tested should be approximately the same as that of the instrument. For optimum results attempt to analyze samples at a concentration of about 10 LEL to 75 LEL. If high concentrations above 10% by volume are analyzed, proper separation between components cannot be observed.
TYPICAL ELUTION TIMES Carrier gas regulator set at 6 P.S.I. Gas Approximate Time Methane 10 - 15 Seconds Ethane 30 - 70 Seconds Propane 3 - 6 Minutes Note: The times shown in the above table is the elapsed times between switching the “Valve” to the “Time” position and the corresponding upscale indications on the display. Note: The material used in the separation column has the property of absorbing and retaining water vapor.
INSTRUMENT RECOMMENDATIONS Hetek recommends that the instrument be kept clean to the typical standards applied to portable gas detection instruments, as well as meeting the requirements for dust, water and gas resistance that are inherent to most handheld instruments. The use of filters, etc. is covered in the Ethane Identifier User Manual.
CALIBRATION VALIDITY The Manufacturer recommends that the instrument be challenged with appropriate calibration gas and the elution times checked for accuracy on annual basis. Instrument should be returned to a qualified service center annually for verification.
MAINTENANCE INSTRUCTIONS Caution: Repair and maintenance beyond that described in this manual should only be performed by qualified personnel. Return to qualified service centre for column replacement. Batteries: If the “Low Battery” LED indicator is solid and bright red, the batteries require replacing. Four (4) “AA” cells power the instrument. Replace the batteries by sliding open the battery access panel at the bottom of the instrument case. Remove old batteries and replace with new batteries.
