I need to analyse Diesel using a gas chromatograph?

This reference contains a simple set of parameters.  Of course, the specific machine and column you use may make these just a starting point to optimize your setup.

You can make your own diesel from used cooking oil.  Most fast food restaurants are glad to give it away because they would otherwise have to pay to have it halled off.  The set-up to convert it will cost between $200-$1000 depending on the method used and how much you want to be able to make at a time.  You can learn more about it here:

No diesel is way too volatile at high temperatures, and also releases a very high concentration of carbon monoxide relative to heating oil-very very dangerous idea.

Download a mpg decompressor. You should find some on google.

Naptha (common usage), gasoline, and diesel fuel are both hydrocarbon chains. Naptha has relatively short chains, probably 6 to 7 carbons long. Gasoline is a little longer, in the 8 carbon region. Diesel fuel, yet again longer. I don't know the average carbon length for Diesel, but I'd guess around 10. The longer the chain, the higher the boiling temp, the higher the flash point, the harder it is to ignite, and the higher the viscosity.\n\nNaptha, as a term used in the US (common usage) typically means the same thing as what was most commonly used as lighter fluid in hand held lighters. In some Euporean countries, it's means an easily flammable, volitile petroleum product, of which, gasoline is one.

Gas-liquid chromatography is useful for a wide range of non-polaranalytes, but poor for thermally labile molecules. \nAtomic absorption spectroscopy reveals identity and concentration of atoms and ions,it does not provide any other information about molecules,bonds etc.

One method is by solubilizing a portion of the polymer and analyzing via GC/Mas spectrometer. Another means would be to burn a portion of the polymer and trap the gases in a trap of sodium hydroxide solution. The solution could then be tested via specific ion electrode and the proportion of flourine could be calculated by knowing the volume of the trap solution, the concentration of fluoride in the trap and the mass of material burned.There are several other means of performing this analysis. One non-destructive test is via X-ray fluorescence. Each element has characteristic fluorescent lines. This method is not terribly sensitive for fluorine but might work well if one was dealing with percentage levels of fluorine.

petrol or gas engine is internal combustion engine that uses ignition spark to ingnite the fuel air mixture. a diesel engine compresses the fuel air to ignite the mixture. petrol.....spark plugs & diesel....no spark plugs

Optical Spectrum Analyzer (OSA) is probably what you're looking for...nice for discovering chemical composition of light source and probably a zillion other different things.

Gas chromatography - specifically gas-liquid chromatography - involves a sample being vapourised and injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself contains a liquid stationary phase which is adsorbed onto the surface of an inert solid.Check out the following site. Describing everything here would go far too long...\n\nhttp://www.shu.ac.uk/schools/sci/chem/tutorials/chrom/gaschrm.htm\n\nHere is a tutorial on how you can interpret the Gas Chromatogram. There are many factors like retention time Rf factor, Rhfactor etc. Please check the following website...\n\nhttp://www.scientific.org/tutorials/articles/gcms.html

Go to biodiesle.com youll find everything you need.

Maybe you should have the emissions checked.  Drive it to the EPA and have them check it out.

Need more specifics as to your problem.\n\nHowever, I assume you are trying to do a quantitation on a UV or vis absorbing substance.\n\nMake up  a set of standards of known concentration of your analyte in the solvent you will be analyzing in.  Then do some scans over the whole wavelength range. \n\nUsually pick the wavelength at the top of the largest absorbance peak, unless that is a wavelength which will have interferences from other substances present.  If so, then pick a wavelength with good absorbance that is not subject to such interference.

try  www.gasbuddy.com  Has charts up to 3 years. Pick your state or province and dont throw something through ur monitor\nwhen seeing the results.

LOL   use the obd??  that not going to tell you much. But then again the question is awfully vague!

To get the most out of it, you need to get the system (kit) that made for your Vehicle.\nGo to this site and look under Air & Fuel Delivery and find Propane Injection, this give some info also\n\nhttp://store.summitracing.com/\n\nAnd this site has all Diesel Injectin system that you need,\n\nhttp://www.dieselperformanceproducts.com/
