4 Ke ʻano hoʻāʻo
4.1 ʻAno
Nānā maka.
4.2 Hoʻoholo maʻemaʻe
4.2.1 Reagents a me nā mea hana
a) Nitrogen: ʻaʻole emi ka maʻemaʻe ma mua o 99.9%, ma hope o ka hoʻomaʻemaʻe ʻana
b) Hydrogen: ʻaʻole emi ka maʻemaʻe ma mua o 99.9%, ma hope o ka hoʻomaʻemaʻe ʻana
C) Air: ma hope o ka hoʻomaʻemaʻe ʻana
4.2.2 Nā mea hana a me nā mea hana
a) Gas chromatograph: hoʻokō ka naʻau a me ke kūpaʻa i nā koi o GB / T9722;
Mea ʻike: hydrogen flame ionization detector;
ʻO ke kolamu kala he SE-54 me ke anawaena o 30m * 0.32mm * 0.4μm.
b) Ka hoʻoili ʻikepili: N2000 chemical workstation, me ka hoʻohana ʻana i ke ʻano maʻamau no ka helu ʻana i ka pakeneka o nā huahana.
c) 10μm mea hoʻohālike.
4.2.3 Nā kūlana hana no ka chromatography kinoea
a) ʻO ke kinoea wela: 250 ℃;
b) ʻIke wela: 220 ℃;
c) Ka wela o ke kolamu: 160 ℃;
d) Ke kaomi kinoea lawe: 0.06MPa;
e) Pumi waihā: 0.1MPa;
f) Pumi ea: 0.2MPa;
g) Ka nui o ka hōʻailona hōʻailona: 0.2ul;
h) Ka manawa mālama: 2.693
ʻO nā mea i luna nei he kūlana hana maʻamau, hiki i nā mea hana ke hana i nā hoʻololi kūpono e like me nā hiʻohiʻona o ka mea kani, i mea e loaʻa ai ka hopena hoʻokaʻawale maikaʻi loa.
4.2.4 Kaʻina hana ana
Ma lalo o nā kūlana chromatographic i luna, ua unuhi ʻia nā laʻana 0.2ul me kahi sampler 10ul ma hope o ka hoʻopaʻa ʻana o ka mea kani, a ua loaʻa ke kiʻi chromatographic.Ua ana ʻia ka maʻemaʻe o ka β-phenylethylamine e ke ʻano hana maʻamau.
4.2.5 ʻAe ʻia ka ʻokoʻa
ʻAʻole ʻoi aku ka ʻokoʻa ma waena o nā hualoaʻa ana like ʻelua ma mua o 0.25%, a ua lawe ʻia ka helu helu helu ma ke ʻano he hopena ana.
4.3 Ka hoʻoholo ʻana i ka ʻae ʻana ma ka ʻupena
Wahi a JJF1070.
5 Nā rula hoʻāʻo
5.1 Pono e nānā ʻia ka β-Phenethylamine e ka ʻoihana nānā ʻoihana maikaʻi, a hoʻopili ʻia i ka palapala hōʻoia ma mua o ka lawe ʻana.
5.2 E hoʻohana ʻia nā huahana hoʻokahi ipu ma ke ʻano he pūʻulu, a ʻo kēlā me kēia pūʻulu o nā huahana ʻaʻole e ʻoi aku ma mua o 1 ton.
5.3 Ke ʻano laʻana
Laʻana e like me GB / T 6680-2003, ʻaʻole emi ka nui o ka hāpana ma mua o 50g.
5.4 I ka wā o ka nānā ʻana, inā ʻaʻole kūpono kekahi mea, ʻae ʻia e hoʻāʻo i ka ʻāpana pālua o ka huahana no ka nānā hou ʻana.Inā loaʻa hoʻokahi papa kuhikuhi kūpono ʻole i ka hopena o ka nānā hou ʻana, e noʻonoʻo ʻia ka pūʻulu o nā huahana ʻaʻole kūpono.
Lepili, hoʻopili, lawe a mālama
6.1 Lepili
E paʻi ʻia a hoʻopaʻa ʻia nā hōʻailona huahana akaka ma nā pahu pahu, me ka inoa o ka huahana, ka maʻemaʻe, ka helu o ka maikaʻi, ka helu maʻamau o ka huahana, ka lā hana, ka helu ʻāpana, ke kaumaha nui a me ka ʻike kaumaha o nā huahana.Pono nā kaha kiʻi mālama me GB/T191.
6.2 Hoʻopili
Hoʻopili pahu pahū
6.3 Kaʻahele
Hiki ke lawe ʻia ka huahana e nā mea maʻamau a me nā ʻano, pono e pale i ka ua, ka wela kiʻekiʻe a me nā ahi ahi, a ʻaʻole e hui pū ʻia me nā mea ʻino a me nā mea e hoʻokuʻu ana i nā kinoea corrosive a i ʻole nāhu.
6.4 Waihona
E mālama ʻia nā huahana i loko o kahi hale kūʻai maloʻo maloʻo a ʻaʻole e mālama ʻia me nā mea ʻino a me nā mea e hoʻokuʻu ai i nā kinoea kino a i ʻole nā ​​​​huhū.
