5.3 Sampling
5.3.1 Sampling is according to GB/T 4756. Take 2L of sample for inspection and
retention.
5.3.2 Sampling shall use amber glass containers. If a metal container is used,
the container shall not have welding. Because the solder will corrode and
dissolve into the methanol fuel, resulting in contamination of the sample. Plastic
containers shall not be used.
5.4 Judgement rules
When the exit-factory inspection results meet the requirements in Table 1, the
batch of products is judged to be conforming.
5.5 Re-inspection rules
If the exit-factory inspection results do not meet the technical requirements of
Table 1, re-extract double samples for re-inspection according to the provisions
of GB/T 4756. If there are still items that do not meet the technical requirements
in Table 1, the batch of products will be judged to be nonconforming.
6 Marking, packaging, transportation and storage
6.1 Methanol gasoline (M85) for motor vehicles is flammable liquid and contains
drugs, which is irritating. Its marking, packaging, transportation and storage and
delivery acceptance are carried out in accordance with NB/SH/T 0164, GB
12268, GB 13690, GB 30000.7 and GB 190.
6.2 Any fuel dispenser pump and container used for methanol gasoline (M85)
for motor vehicles sold to users that comply with this Standard shall be marked
with "Methanol gasoline for vehicles (M85)". According to GB 12268, GB 13690,
GB 30000.7 and GB 190, flammable liquids and signs of drugs shall be marked.
The above signs shall be marked in a place that is easily visible to the driver of
the vehicle.
6.3 Methanol gasoline (M85) for motor vehicles conforming to this Standard
shall use special pipes, containers and pumps during transportation and
storage. The seals and materials of these storage tanks, pumps, pipelines, and
gauges shall meet the requirements of methanol gasoline (M85) for motor
vehicles. During storage and transportation, ensure that the entire system is
clean and free of water. At the same time, the inhalation of external water shall
be strictly prevented. A breathing valve with desiccant must be installed on the
finished product storage tank. If phase separation occurs, special handling shall
be performed.
6.4 Unprotected aluminum and unlined nitrile rubber dispensing hoses shall be
avoided in dispensing and metering systems for methanol gasoline (M85).
NOTE: The use of unprotected aluminum components in dispensing and metering
equipment for methanol gasoline (M85) for motor vehicles can lead to insoluble aluminum
compounds entering the fuel and clogging automotive fuel filters. Also, even with protective
aluminum components, this corrosion effect is exacerbated by the increased conductivity
of the fuel due to the fuel's contact with the nitrile rubber dispensing hose.
7 Safety
7.1 The data and information related to safety in the transportation, storage,
use and accident handling of methanol gasoline (M85) for motor vehicles shall
be included in the "chemical safety data sheet" of the product. Manufacturers
or suppliers shall provide their product "chemical safety data sheet" prepared
in accordance with GB/T 17519.
7.2 Methanol vapor in methanol gasoline (M85) for motor vehicles has a
stimulating effect on the nervous system. Inhalation into the human body can
cause blindness and poisoning. Therefore, when loading, unloading and
refueling, try to reduce the volatilization of methanol gasoline (M85) vapor for
vehicles. Mouth, eyes and skin shall not come into contact with this product.
Avoid breathing methanol gasoline (M85) vapors for vehicles. Preparation,
loading and unloading, refueling personnel shall take corresponding protective
measures. Avoid excessive inhalation of harmful vapors.
7.3 Once the methanol gasoline (M85) for motor vehicles is splashed into the
skin and eyes, rinse immediately with plenty of water and seek medical attention
immediately.
7.4 It shall not use mouth suction for methanol gasoline (M85) for motor vehicles.
Do not use methanol gasoline (M85) for motor vehicles to wash hands, scrub
clothes, machine parts, fill lighters and use as fuel for torches.
7.5 When using methanol gasoline (M85) to catch fire, use sand, fluoroprotein
anti-solvent foam fire extinguishing agent, asbestos cloth and other fire
extinguishing materials for firefighting. When methanol gasoline (M85) for motor
vehicles overflows, special treatment shall be carried out.
A.4.4 Nitrogen: Purity is 99.998% (volume fraction); used to prepare TCEP
micro-packed columns.
WARNING - Pressurized gas.
A.4.5 Tert-amyl alcohol (2-methyl-2-butanol): Purity is above 99% (mass
fraction); used as the internal standard.
WARNING - Flammable and harmful to health.
A.5 Column packing preparation
A.5.1 TCEP packed column preparation
A.5.1.1 Any column can be used as long as it can retain methanol and tert-amyl
alcohol (internal standard) in methanol gasoline (M85) from hydrocarbons in
the same boiling range.
A.5.1.2 10g of TCEP is dissolved in 100mL of dichloromethane. Then add 40g
of 150μm~180μm (100/80 mesh) red diatomite carrier P(AW) to the above
solution. Quickly transfer these mixtures to an evaporating dish and place in a
fume hood. There is no need to wipe off the residual filling deposited on the
container. Continuously and gently stir the filling until all solvents are
evaporated. The column packing can be used directly to prepare TCEP
columns.
A.5.2 Packing of micro-packed column TCEP
A.5.2.1 Use methanol to wash a stainless-steel column tube with a length of
560mm and an outer diameter of 1.6mm (inner diameter of 0.3mm). Then use
compressed nitrogen to dry.
A.5.2.2 Insert a plug made of 6-12 silver-plated wires or stainless-steel mesh
into one end of the column tube. Slowly add 0.14g~0.15g of packing material
to the other end of the column. Shake the column gently during the filling
process to pack the packing. And add a plug to the charging end. When
plugging the column with wire or stainless-steel mesh plug, leave 6.4mm at both
ends of the column to ensure that the packing does not flow out.
A.5.2.3 Both TCEP and WCOT columns shall be briefly conditioned before use.
Connect the column to the valve in the column oven (see A.7.1). Adjust the
carrier gas flow according to A.7.3. Put the valve in the reset position. After a
few minutes, increase the oven temperature to 120°C, and keep it for
5min~10min. Cool the column to 60°C before turning off the carrier gas.
A.6 Sampling
A.6.1 To obtain a representative sample for testing, use the procedure specified
in GB/T 4756 for sampling.
A.6.2 Methanol gasoline (M85) samples for motor vehicles shall be stored in a
refrigerator until the time of testing. If it cannot be analyzed immediately, the
sample shall be placed in the refrigerator.
A.6.3 The sample container shall be sufficiently shaken before taking the
sample for analysis. Allow particles to settle at the bottom of the sample
container. Observe the samples for significant phase separation. If so, the
sample will be discarded and a re-collection of the sample will be required.
A.7 Instrument preparation and conditioning
A.7.1 Assembly
Use low-volume connectors and fine bore tubing to connect the WCOT column
to the valve system. It is important to minimize the dead volume of the
chromatographic system connections, otherwise the chromatographic peaks
will be broadened.
A.7.2 Operation conditions
Adjust operating conditions according to Table A.1 (if using a TCD, do not open
the detector circuit). The system shall be tested before operation.
A.7.3 Adjustment of split ratio
A.7.3.1 See Figure A.1 for split ratio adjustment.
A.7.3.2 Set the valve in reset position. Install a soap bubble flowmeter at the
column vent. Adjust the injection port pressure to a flow rate of 5.0mL/min.
A.7.3.3 Install the flowmeter in the vent of the split vent. Use a gas path flow
controller to adjust this flow to 70mL/min. If necessary, recheck the outlet flow
in accordance with A.7.3.2.
A.7.3.4 Switch the valve to the backflush position. Adjust the resistance valve
to make the column outlet flow the same as A.7.3.2. This is necessary to
minimize flow changes when the valve is switched.
A.7.3.5 Switch the valve to the injection reset position. Adjust the B flow
controller so that the flow at the detector outlet is 3.0mL/min~3.2mL/min.
According to specific instrument needs, add auxiliary gas or TCD flow, so that
the total flow at the detector outlet is 21mL/min.
A.7.4 Detector
When using a thermal conductivity detector, open the thermal conductivity
