APPENDIX A

METHOD OF TEST FOR ANALYSIS OF GRADE JP-10 FUEL BY GAS

CHROMATOGRAPHY

A.1 SCOPE

A.1.1 Scope

A.2 SUMMARY

. This method provides for the quantitative determination of the purity of exo-tetrahydrodicyclopentadiene, the single chemical structure of JP-10. This Appendix is a mandatory part of the specification. The information contained herein is intended for compliance.

A.2.1 Summary of methods

A.3 APPARATUS

. The sample is introduced into a gas chromatograph column, which has been calibrated with a pure sample of exo- tetrahydrodicyclopentadiene, (4.5). The detector signal is monitored continuously and the areas of individual peaks are used for computing the quantities of the JP- 10 and other hydrocarbon impurities. The detailed composition of the JP-10 component is computed from the individual peak areas in the subgroup.

A.3.1 Chromatograph

A.3.1.1

. Any conventional gas chromatograph, having at least the following features, is acceptable.

Detector

A.3.1.2

. A thermal conductivity (TCD), flame ionization (FID), or mass spectrometer (MS) detector may be used. The detector shall be operated in such a manner that its linear dynamic range is not exceeded, and its linearity should be checked periodically. The detector shall be capable of continuous operation, and must be connected to the column in a manner that eliminates cold spots.

Temperature Programmer

A.3.1.3

. The instrument must be capable of reproducible temperature programming over the range of 50⁰C to 300°C. The programming rate must be sufficiently reproducible so that individual retention times do not vary by more than 2 percent. Any temperature program, including multilinear modes and intermediate periods of isothermal operation, is acceptable, provided that the column resolution, as defined in section A.5.2, is not compromised. If capillary-type columns are used for the analysis, it may not be necessary to program the oven above 200°C.

Sample inlet system

A.3.1.4

. Either flash vaporization or on-column injection may be used. For flash vaporization, the sample inlet port must be maintained between 250° and 300°C, and well-conditioned septa must be used. If on-column injection is employed, provision must be made for programming the temperature of the full length of the column. A sample inlet splitter may be used in conjunction with capillary columns, if care is taken to ensure that a representative sample is delivered to the column. New septa should be allowed to condition overnight after being installed in order to minimize spurious peaks, and several blank runs should be made to purge the column of materials bleeding from the septum. Overnight conditioning can be eliminated by the practice of storing a supply of septa in the column oven. However, at least one blank run should still be made following each septum change.

Column

A.3.1.5

. Either packed or open-tubular (capillary-type) columns may be used, provided the minimum resolution, specified in A.5.2, is maintained. The column should be designed for maximum thermal stability and minimum bleed, since the temperature program is likely to run as high as 275°C for packed columns and 200°C for capillary columns. Dual-column compensation is required if column bleed results in excessive baseline drift at high temperature.

Data Acquisition

A.3.1.6

. Computer controlled data acquisition and integration is the preferred method of data collection and analysis. The computer system must be designed and calibrated for gas chromatograph operation. An electric data recorder / integrator may be used if necessary.

Microsyringe. A microsyringe, capable of delivering sample volumes from 0.5 to 5.0 microliters, is required for FID and TCD detectors. The widely used 0 – 10 microliter syringe, Hamilton Model 701N or its equivalent, is recommended. A microsyringe, capable of delivering sample volumes from 0.1 to 0.5 microliters, is required for MS detectors. These syringes are routinely available from most instrument manufacturers and chromatography supply houses.

A.4 REAGENTS AND MATERIALS

A.4.1 Stationary phase

100% Dimethylpolysiloxane

. The stationary phase should be one of the familiar non-polar polysiloxanes, or equivalent. The following columns have been used successfully:

(5%-Phenyl)-methylpolysiloxane

Either of the listed phases is satisfactory, provided baseline drift at high temperatures is maintained by conditioning or by dual-column compensation.

A.4.2 Carrier gas

A.4.3

. Either helium or nitrogen is suitable for FID detectors, although nitrogen is known to give somewhat higher column efficiencies at lower flow rates, and is more economical. Helium must be used with thermal conductivity detectors. Either helium or hydrogen may be used with a mass spectrometer detector. The flow must be maintained constant to within one percent throughout the entire range of operating temperatures by means of constant flow controllers.

Hydrogen

A.4.4

. High purity, for flame ionization detectors.

Air

A.4.5

. Dry, filtered, and oil-free, for flame ionization detectors.

Exo-tetrahydrodicyclopentadiene

A.4.6

. Minimum ninety-nine weight percent purity, hereafter referred to as C-10.

N-pentane, n-hexane, or petroleum ether

A.4.7

. Chromatographic purity.

Qualitative calibration mixtures

A.5 PREPARATION OF APPARATUS

. A series of known hydrocarbons is used for calculating column resolution. Prepare a mixture containing about one percent (by volume) each, in pentane or hexane, of at least eight normal alkanes from highly pure (minimum 99 percent) samples which have boiling points in the 70°C to 250°C range. The mixture must contain n-dodecane and n-tetradecane.

A.5.1 Column

A.5.2

. Any conventional method of conditioning and installing the column is satisfactory, provided the system is free of gas leaks and the column resolution meets the minimum requirement specified in A.5.2.

Column resolution

1214 RT- RT 2R

WW +

. Run a sample of the qualitative calibration mixture and measure the retention times and widths of the n-dodecane and n-tetradecane peaks as shown on Figure A1.

Resolution is defined as the difference in retention times for n-C12 and n-C14 divided by their average width:

Resolution determined in this way must be at least 5.0 and can be optimized by varying the temperature program and the carrier flow rate. If resolution cannot be increased to at least 5.0 by optimizing these parameters, it is necessary to use a difference column.

A.5.3 Chromatograph

A.6 PROCEDURE

. Place in service according to the manufacturer's specifications paying particular attention to flow rates through the detector.

A.6.1 Suitable sample. Establish a suitable sample volume by making several trial runs with the qualitative calibration mixture. For FID instruments, the volume may be between 0.5 and 1.0 µL. For TCD instruments, volumes from 1.0 to 5.0 µL have been found satisfactory. For MS instruments, volumes from 0.1 to 0.25 µL have been found satisfactory.

A.6.2 Acceptance sample

A.6.3

. Dilute an aliquot of the JP-10 acceptance sample at least 1:10 (preferably 1:20) with pentane, hexane, or petroleum ether. Mix thoroughly and inject a measured volume into the chromatograph, simultaneously activating the temperature program, the integrator, and the recorder.

Integration

A.7 CALCULATIONS

. Integrate the area under the chromatogram continuously until the final peak has been eluted. C-10 extra peaks which are within plus or minus ten percent of the retention time for C-10 shall be considered part of the C-10 peak if they do not contribute more than 20 percent to the total C-10 peak areas. A typical GC/MS chromatogram is included as Figure A2.

A.7.1 Weight percent

AA

A 10-C % impurties10-C

10-C ×

. For each JP-10 acceptance sample, calculate the weight percent of C-10 as follows:

In the above equation, all hydrocarbons other than those contained in the C-10 subgroup are considered impurities. A response factor of 1.000 is used for the impurities.

A.8 PRECISION

A.8.1 Studies

A.8.1.1

. Detailed precision studies have not been performed for this method. However, limited results indicate that the method is capable of the following precision.

Repeatability

A.8.1.2

. Replicate analyses, performed under identical conditions in the same laboratory, should yield results that do not vary more than 1 percent (absolute) from the mean value for each component.

Reproducibility

A.8.1.3

. When the same sample is analyzed in different laboratories according to this method, the results for any component should not differ by more than 1.5 percent (absolute).

Accuracy

. Back-analysis of a calibration standard should give results that agree with the known values to within 0.5 percent (absolute).
