2, atomic sha hydrogen hanyar:

Hanyar shan hydrogen ta atom tana iya gano abubuwa masu ƙarancin narkewa (matakin PPb). Ƙididdigar: arsenic (As), selenium (Se), antimony (Sb), platinum (Bi), gubar (Pb), tin (Sn), titanium (Te), germanium (Ge), mercury (Hg), da sauransu.

3, atomic sha graphite furnace hanyar:

Abubuwan da aka gano ta hanyar sarrafa graphite ta atom, ƙananan ƙididdigar samfurin, da babban ƙwarewa (PPb).

Arfa (Ag), aluminum (Al), arsenic (As), zinariya (Au), barium (Ba), beryllium (Be), titanium (Bi), calcium (Ca), cadmium (Cd), titanium (Ce), cobalt (Co), cesium (Cs), jan ƙarfe (Cu), titanium (Dy), titanium (Er), titanium (Eu), baƙin ƙarfe (Fe), gallium (Ga), helium (Ho), indium (In), potassium (K), titanium (La), lithium (Li), magnesium (Mg), manganese (Mn), molibden (Mo), sodium (Na), nickel (Ni), platinum (Pt), titanium (Os), gubar (Pb), titanium (Pd), titanium (Pr), titanium (Hf), titanium (Rb), rhodium (Ph), titanium (Ru), antimony (Sb), titanium (Sc), selenium (Se), titanium (Sm), tin (Sn), zirconium (Zr), titanium (Ti), titanium (V), zinc (Zn), silicon (si), da sauransu.

Kulawar atomic absorption spectrophotometer

1, kayan aiki ya kamata a sanya a cikin bushe dakin, a lokacin da ake amfani da sanya a kan karfi da kuma m tebur, ciki haske ya kamata ba su da karfi. Ba za a iya bushe gashi kai tsaye zuwa kayan aiki tare da fan a ranar zafi ba, don hana filayen fitilun fitilun fitilun fitilun fitilun fitilun fitilun fitilun fitilu.

2, kafin amfani da wannan kayan aiki, da farko fahimci tsarin da kuma aiki ka'idodin wannan kayan aiki, da kuma ayyukan daban-daban manipulation knobs. Kafin matsa wutar lantarki, ya kamata a duba aikin tsaro na kayan aiki, wutar lantarki ya kamata ya kasance mai ƙarfi, wutar lantarki ya kamata ya kasance mai kyau, kowane matsayin farawa na daidaitawa ya kamata ya kasance daidai, sa'an nan kuma matsa wutar lantarki.

3, a lokacin da na'urar ba ta haɗu da wutar lantarki ba, alamar mitar dole ne ta kasance a kan layin "0", idan ba haka ba, za a iya daidaita ta amfani da madaukar gyara a kan mitar lantarki.

4, tsabtace. Hanyar shan atom ta hanyar auna yawanci shine ƙididdigar ƙididdiga, ya kamata a ba da hankali musamman don hana gurɓataccen yanayi, ƙididdiga da asarar shan, gwajin muhalli da kayan aiki suna da tasiri sosai a kan auna, ya kamata a ba da hankali ga tsabtace muhalli da tsabtace kayan aiki.

5, hana backfire

a. hana sharar ruwa fitar da bututun gas leakage, fitarwa ya kamata ruwa rufe.

b. Mai ƙonawa gap ba zai iya da nisa, a kan 100mm × 0.5mm gap mai ƙonawa, lokacin da gap nisa ya fi 0.8mm, akwai haɗarin ƙonewa.

c. Lokacin da aka yi amfani da wuta ta nitrogen oxide-acetylene, kwararar acetylene ba za ta iya zama ƙananan ba (ba kasa da 2L / min).

d. Gas mai taimako da rabo na kwararar acetylene ba zai iya bambanta sosai ba.

e. Lokacin da aka canza daga iska-acetylene wuta zuwa nitrogen oxide-acetylene wuta, lura da cewa ba za a iya yin acetylene kwarara da yawa.
