PROJECT EXPERIENCE SECTION OF THE QSTI/QSTO

PROJECT EXPERIENCE SECTION OF THE QSTI APPLICATION - EXAMPLE  - For those persons who have taken the exam (or plan to) and are preparing their applications for submittal to the QSTI Review Committee, the project experience section may prove a little open-ended. What are “they” looking for? How much information should I include? Do “they” want a copy of a test report? First, definitely do not send in any test reports. The committee is not equipped to handle such confidential business information. What the committee does need is information about your experience and knowledge sufficient to demonstrate that you can conduct a test project successfully and produce reliable results. As a guideline for completing this element of the application, the QSTI Review Committee has provided two examples for your use. The components of these examples coincide with those outlined in the SES application form. Group II Application (example 1)  Project One  EPA Method 7  I led a project to measure NOx em

How To Calibration Toxic Vapor Analyzer 1000B?

TVA1000B Quick Start and Calibration Guide

1. Install filled hydrogen tank, attach probe/readout assembly, turn on analyzer and
hydrogen supply valve.
2. Wait 4-5 minutes for proper hydrogen flow, then press 1 = Run. The unit will ignite
and display readings. If flame out message appears, clear the message (press Exit),
wait another minute and repeat step 2. If the unit has not been properly calibrated, a
bad calibration parameter error appears – go to step 3 below.
3. Press Exit until the Main Menu appears. Calibration can now be performed. For
best results, allow unit to warm up for 20 minutes, then press 2 = Setup.
4. Press 1 = Calib.
5. Press 2 = SpanConc.
6. Select the detector that the span concentration is for, then press the ↑ or ↓ arrow to
select the correct unit of measure for the span gas. Enter the span calibration value,
and press the Enter key. Repeat steps 5 & 6 for the second detector. Typically, the
calibration gases are methane (FID) and isobutylene (PID).
7. Next zero the instrument. Press 3 = Zero to start this process.
8. Press 1 = Both for dual detector units, or Enter for single detector units.
9. Introduce zero gas (< 1 ppm total hydrocarbon) into the analyzer through the probe.
10. Press Enter to start (this assumes manual mode, the factory default).
11. Wait for minimal change in values (about 15 seconds). Typically, the sample is
stable when the first 2 digits of the reading do not change for 4-5 seconds.
12. Press Enter to accept, then press 1 to save.
13. Next calibrate with the span gas. Press 4 = Span.
14. Select the detector to be calibrated, and press Enter to start. Follow the screen
prompts. Wait for the readings to stabilize (typically 10-15 seconds). Enter 1 to
save and repeat steps 13 & 14 for the second detector.
15. Press 5 = RF to verify proper response factor.
16. Confirm that response factor says “RF0: DEFAULT”. If not, set to this value.
17. Press Exit twice to return to MAIN MENU.
18. Press 1 = Run.
This completes the primary calibration, and the instrument is in the survey mode.

Sources of Air Pollution are four mobile sources, stationary sources,point sources andarea sources

 Sources of Air Pollution In discussions of air pollution sources, four terms are routinely used:  Mobile sources  Stationary sources  Point sources  Area sources  Mobile sources Mobile sources are generally related to transportation. Mobile sources are not included within the general parameters for fugitive emissions and, therefore, will be given no further consideration in this course.  Stationary sources Stationary sources define emission sources that are fixed and include all forms and types of manufacturing, chemical and petroleum processing, power generation, and small business facilities. Point sources A stationary point source refers to any place within a facility from which emissions are possible. For a given facility, a stack may be one point source. An emission leak within a process is also considered a point source. An automobile or a truck would represent a point source or mobile source. Area sources Area source refers to any one of several sources contributing to the air

Dual Detectors FID and PID

Dual Detectors The benefits of each individual detector are very clear: both the FID and the PID have their  advantages and disadvantages. However, with either detector alone, the number of organic  and inorganic vapors that one can detect is limited by the measurement capabilities of that  detector. With the TVA-1000B, users can obtain complete information about more organic and inorganic  vapors more quickly and easily than with single detector technology alone. Since both detectors may be displayed and logged simultaneously, the relative response of the  two detectors may give some clues about the identity of the compound being measured. For  instance, the PID does not respond to methane at all, but the FID responds very well. A high  FID reading with virtually no PID response might indicate the presence of methane. Consequently,  PIDs respond very well to some inorganic gases that FIDs cannot detect. A high PID  reading with no FID reading might suggest the presence of an i
