4 Reagents and materials
Unless otherwise specified, water GB/T 6682 provided a water, reagents were of analytical grade.
4.1 ethylene oxide standards. purity of greater than 99%.
4.2 propylene oxide standards. purity of greater than 99%.
Ether 4.3 Standard. purity of more than 99.5%, the chromatogram with ethylene oxide or propylene oxide with the same retention time of the impurity peak area not
Exceed 1%.
When the purity is greater than 99.9%, the chromatogram of ethylene oxide or propylene oxide with the same retention. 4.4 N, N- dimethylacetamide (DMAC)
Between the impurity peak area shall not exceed 1%.
4.5 ethylene oxide standard stock solution (2mg/mL ~ 6mg/mL). amount of 50mLDMAC (4.4) in 50mL vial (5.3), and
Weighed (accurate to 0.0001g). To join in the vial 0.1g ~ 0.3g of ethylene oxide (4.1), immediately sealed Mix thoroughly weighed
(Accurate to 0.0001g). Calculate the actual concentration of ethylene oxide standard stock solution. Solution should be protected from light at 4 ℃ sealed storage, valid for
Two months.
4.6 propylene oxide standard stock solution (1mg/mL). Weigh 50mg (accurate to 0.0001g) of propylene oxide (4.2) in a pre-filled with 30mL
DMAC of 50mL volumetric flask, using DMAC volume. Calculate the actual concentration of propylene oxide standard stock solution. The solution was stored Article
Member with 4.5.
4.7 ethylene oxide intermediate standard solution (0μg/mL ~ 40μg/mL). amount of each 8mLDMAC to six 10mL volumetric flask,
Then were added with a micro-syringe (5.2) an amount of ethylene oxide standard stock solution (4.5), the DMAC volume. Ethylene oxide standard stock
