StarVOC - On-Line HRVOC Analyzer
The StarVOC HRVOC analyzer provides automatic, on-line analysis of total or speciated volatile organic compounds for compliance with EPA and local emission regulations. The new rules do not require speciation, if an HRVOC analyzer is used, thus eliminating the complexity, cost, and interference problems of GC/FID analysis.
A speciation module is offered as an option to facilitate plant troubleshooting, during “release” events. Automatic validation and reporting, automatic calibration, and onboard historical data archives provide all appropriate certification records for future government review.
The analyzer is totally automatic. No expensive or hazardous gases are needed and the use of the familiar Microsoft Windows operating system affords ease of operation, training, and service.
System design affords totally automatic compliance testing, calibrating, and data reporting through the use of its own operating platform. It utilizes approved water sampling techniques for cooling tower applications and a combined calorimeter/HRVOC analyzer system for flares.
Quality Assurance and Quality Control requirements are maintained automatically, primarily through onboard computer control and data archives. Star has developed a comprehensive QA plan andValidation Protocols, with defensible reporting on a continuous basis.
Optional Speciation Module allows individual HRVOC species analysis through the use of an internal GC separation column. This is especially helpful in quickly determining process leaks for rapid remediation. It avoids alternative “grab” sampling techniques and laboratory GC analysis. Automatic switching to the GC column is accomplished by computer control after specified total HRVOC levels are exceeded.

The NAMUR specified validation technique is used, whereby on comuter command a calibration standard is automatically introduced to the analyzer and the response is compared to the previous analyzer calibration. If the response falls outside specified performance limits, either a “Maintenance Request” or a “Fault” alarm is activated, depending on preset tolerances. Auto-Calibration is computer controlled nd is performed on a multi-level basis:
1. Sensor
2. Analyzer “end-to-end ”Total HRVOC”
3. Analyzer “end-to-end” speciated VOC (if onboard Speciation Module used.
Star analyzers use Microsoft Windows CE to ensure that you are always up-to-date with the latest technologies. Operator training is minimal. By incorporating a modular software design, Star is capable of offering advanced options unavailable elsewhere.
Windows CE Computer with Touch Screen Control
- Touch Screen
- VGA Color Display
- Network Ready
- Paperless Chart Recorder
- PCMCIA Slot
- Solid State Data Storage
Star’s utilization of an onboard Windows CE computer allows direct networking. Central control of analyzer operation and data mangement are easily facilitated.
The photoionization detector is the VOC detector of choice by the USEPA, because of its superior sensitivity (100:1 over FID) and se;ectovotu/ Ot os ,amdated for use in the following methods:
- TO-14A 502.1
- 602 502.2
- 8020A
The PID UV lamp irradiates incoming gas from either the sparger or flare directly (VOC-Total) or the column (VOCSpeciated). The UV energy ionizes the molecules, producing an ionic current (R + hv R+ + e-) which is measured by the electrometer and computed in units of ppbw.
NOTE: Because the PID is non-destructive, an FID or other detector may be placed in series with it, offering dual detectors
Star furnishes recommended installation drawings. The user must provide the following:
1. Electrical source (110/220 VAC 300 watt service with external cutoff switch).
2. Sample flow of a minimum of 25mL/minute. A fast bypass loop is recommended.
3. Gravity fed drain with air break.
4. A source of hydrocarbon-free air with a maximum flow rate of 100cc/min @ 15 psig.
5. Calibration gases, as specified.
Star’s distribution network offers complete installation assistance and operator training. Star also offers an on-site Certification Program, whereby Star will provide Installation and Operation Protocols (IOPs) and Standard Operating Procedures (SOPs) and will factory certify both the installation and system performance as fully compliant with government regulations.
The STAR PARTS EXCHANGE SERVICE PROGRAM provides the CUSTOMER with the fastest, most reliable and cost effective method to service any malfunctioning component. All modules can easily be replaced within 15 minutes, allowing “up time” functionality on the order of 98%.
