--Dexsil’s PetroFLAG Total Petroleum Hydrocarbon (TPH) in Soil System is an on-site test kit for determining the total petroleum hydrocarbons in soil. It is easy to use, inexpensive, and environmentally safe. The PetroFLAG System does not distinguish between aliphatic and aromatic hydrocarbons, but quantifies all oils, greases, and fuels as total hydrocarbons. Analysis is performed using a 10 gram soil sample and three easy steps: extraction, filtration, and analysis.
++Dexsil's PetroFLAG Total Petroleum Hydrocarbon (TPH) in Soil System is een on-site testkit voor het bepalen van de totale hoeveelheid aardoliekoolwaterstoffen in de bodem. Het is gemakkelijk te gebruiken, goedkoop en milieuvriendelijk. Het PetroFLAG-systeem maakt geen onderscheid tussen alifatische en aromatische koolwaterstoffen, maar kwantificeert alle oliën, vetten en brandstoffen als totale koolwaterstoffen. Analyse wordt uitgevoerd met behulp van een grondmonster van 10 gram en drie eenvoudige stappen: extractie, filtratie en analyse.

--The microprocessor in the PetroFLAG analyzer uses the calibration data to convert the optical reading into a preliminary concentration. The selected response factor is then used to calculate the correct concentration for the analyte of interest. Therefore, it is important to choose the response factor that is appropriate for the particular hydrocarbon or class of hydrocarbons present at the site. The response factor can be changed at any time without affecting the stored calibrations.
++De microprocessor in de PetroFLAG-analysator gebruikt de kalibratiegegevens om de optische meetwaarde om te zetten in een voorlopige concentratie. De geselecteerde responsfactor wordt vervolgens gebruikt om de juiste concentratie voor de van belang zijnde analyse te berekenen. Daarom is het belangrijk om de responsfactor te kiezen die geschikt is voor de specifieke koolwaterstof of klasse van koolwaterstoffen die op de locatie aanwezig is. De responsfactor kan op elk moment worden gewijzigd zonder de opgeslagen kalibraties te beïnvloeden.
--If the contaminant is known or suspected, choose the appropriate response factor from the following table and set that response factor on the analyzer. If there is a mixture of hydrocarbons, use the most conservative response factor for the contaminants known to be present. If the contaminants are unknown, choose a conservative response factor based on those hydrocarbons that are likely to be on the site. Examination of Table 1, indicates that the majority of typical contaminants are in response category 5 or above. [[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]
++Als de verontreiniging bekend is of vermoed wordt, kiest u de juiste responsfactor uit de volgende tabel en stelt u die responsfactor in op de analysator. Als er een mengsel van koolwaterstoffen is, gebruik dan de meest conservatieve responsfactor voor de verontreinigingen waarvan bekend is dat ze aanwezig zijn. Als de verontreinigingen niet bekend zijn, kies dan een conservatieve responsfactor op basis van de koolwaterstoffen die zich waarschijnlijk op de locatie bevinden. Onderzoek van tabel 1 geeft aan dat de meeste typische verontreinigingen in responscategorie 5 of hoger zijn. [[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]

--The PetroFLAG Hydrocarbon Analyzer is preprogrammed to warn the user of an over-range condition. If the over-range reading is outside of the linear range (±10 precision), but still within the quantifiable range (±20% precision), the reading will be displayed blinking. This reading can be used as an indication that the concentration in the sample is not less than the displayed value. Since the response curve for most analytes is non-linear at high concentrations, the concentration in the sample may be higher than the displayed value. If the over-range condition is outside of the quantifiable range of the meter, the display will show a blinking "EEEE". Either error indication can be cleared by simply inserting the next vial and pressing the key. Accurate results can be difficult to obtain when 10 gram soil samples with high contaminant concentrations are used since they may cause a over-range condition on the PetroFLAG analyzer. To quantify these high contaminant samples, extract fresh soil samples of 1 gram size and reanalyze. Then multiply the result by 10 to obtain the concentration in the sample. Using this procedure, it is possible to measure oils containing up to 50,000 ppm of light hydrocarbon contamination or 10,000 ppm of a heavier hydrocarbon. [[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]
++De PetroFLAG Hydrocarbon Analyzer is voorgeprogrammeerd om de gebruiker te waarschuwen voor een overschrijding van het bereik. Als de meetwaarde buiten het lineaire bereik valt (±10 precisie), maar nog steeds binnen het kwantificeerbare bereik (±20% precisie), wordt de meetwaarde knipperend weergegeven. Deze aflezing kan worden gebruikt als een indicatie dat de concentratie in het monster niet lager is dan de weergegeven waarde. Aangezien de responscurve voor de meeste analyten bij hoge concentraties niet-lineair is, kan de concentratie in het monster hoger zijn dan de weergegeven waarde. Als de overschrijdingsconditie buiten het kwantificeerbare bereik van de meter valt, toont het display een knipperende "EEEE". Beide foutindicaties kunnen worden gewist door simpelweg de volgende flacon te plaatsen en op de toets te drukken. Nauwkeurige resultaten kunnen moeilijk te verkrijgen zijn wanneer grondmonsters van 10 gram met hoge concentraties verontreinigende stoffen worden gebruikt, aangezien deze een overschrijding van het bereik op de PetroFLAG-analysator kunnen veroorzaken. Om deze monsters met een hoge verontreiniging te kwantificeren, extraheert u verse grondmonsters van 1 gram en analyseert u deze opnieuw. Vermenigvuldig vervolgens het resultaat met 10 om de concentratie in het monster te verkrijgen. Met deze procedure is het mogelijk om oliën te meten die tot 50.000 ppm lichte koolwaterstofverontreiniging of 10.000 ppm zwaardere koolwaterstof bevatten.[[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]

--== The effect of temperature ==
++== Het effect van temperatuur ==
  The PetroFLAG analyzer is equipped with an onboard temperature sensor to measure the ambient temperature while measurements are being made. The software uses the temperature readings to correct the optical readings for drift caused by the temperature fluctuations. The corrections have been determined for their effects on the turbidity development and the temperature drift of the electronics. The PetroFLAG analyzer can be used at temperatures from 4^^o^^C to 45^^o^^C.

  As previously mentioned, the storage of two calibrations, each at a different temperature, will reduce the number of recalibrations necessary as the temperature changes. If the two calibrations are stored under “1C” and “2C” and are run at temperatures levels 20^^o^^C apart, the effective temperature range for measurements now becomes 40^^o^^C.[[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]
--== The effect of soil water content ==
++== Het effect van grondwater ==
  The presence of water in a soil sample will have a definite effect on the reporting value in the final PetroFLAG result. As with all field measurements, the PetroFLAG system result is calculated based on the sample weight “as received”. If there is water present in the sample, this will produce a “wet weight” result causing an apparent under reporting by the PetroFLAG technique when compared to a laboratory reporting on a “dry weight” basis.

  Treatment with sodium sulfate can improve the extraction efficiency, but will not correct for either the dilution effect or the wet weight/dry weight reporting error. The actual water content in the sample should be determined at some point so that the above corrections for wet weight and the dilution effect can be applied to the final result.[[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]
--== Sample preparation ==
++== Voorbereiding monster ==
  Each 10-pack of soil reagents contains reagents and supplies for 10 tests. In addition, one blank and one calibration standard are included. Samples can be run individually or by batch. For optimum performance and throughput, samples should be run in groups of 10 samples, once the meter has been calibrated with a blank and a standard. The meter does not need to be recalibrated, provided that the operating conditions and reaction times are maintained. Total time to analyze 10-15 samples is approximately 20-25 minutes.[[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]

++== Calibratie ==
  The following description summarizes the procedure for preparing the blank and calibration standard. Read the step-by-step instructions below completely before beginning the calibration process. To prepare a blank and a calibration standard, first label two soil tubes, one as the "blank" and the other as the "standard". Add to the blank tube the contents of a break-top ampule labeled “Extraction Solvent”. Add the contents of the break-top ampule labeled "Calibration Standard" to the standard soil tube. Process the blank and standard exactly as soil samples as described below.[[[2]>>url:https://www.equipcoservices.com/pdf/manuals/dexsil_petroflag_system.pdf]]
