Te whakamahi i te pūwhakataka whai tohu ine mō te kahurangi metilēni: te pānui tika i ngā rōrahi

Ka ine te pūwhakataka whai tohu ine i te rōrahi wai. Kia mōhio ai koe ki te rahinga kahurangi metilēni i taua rōrahi, me mōhio hoki koe ki te kukū kua tohua mō te wairewa. Kāore te pūwhakataka, te tātaitanga rānei, e whakaatu ana i te rahinga e tika ana kia tangohia e te tangata.

Tīmata ki ngā pātai motuhake e toru: He aha te waeine kua tāngia ki te taha o ngā tohu? Ko tēhea tohu ka tae atu te wai? E hia ngā mirikarama kei ia miririta, e ai ki te tapanga? Mā te wehe i aua pātai e karo ai tētahi hapa noa: te whakaaro he rahinga ōrite te pata, te miririta me te mirikarama.

Ngā mea e whakaūngia ana e te rārangi hua

E kī ana te rārangi wairewa ā-wai Blupreme 100 mL ko te kukū he 1% taumaha mō ia rōrahi, e ōrite ana ki te 10 mg/mL, ā, e whakaahua ana i tētahi pūwhakataka kua whakaurua, he tohu kei te 0.25 mL, 0.5 mL, me te 1 mL. Ko te tau 100 mL e whakaahua ana i ngā mea kei roto i te pounamu; ko ngā tau iti iho e whakaahua ana i ngā rōrahi kua inea i roto i te pūwhakataka.

Whakamahia te tapanga me te taputapu i tukuna mai me tō ake pounamu. Kāore tētahi whakaahuatanga hua e whakaū ana i te awhe hapa e whakaaetia ana mō te whakatikatika ine o tētahi pūwhakataka takitahi. Kāore te rārangi kua whakaputaina e whakarato ana i tētahi whakaritenga ā-tau mō te tika o te ine, nō reira kaua e whakaaro ko te noho o tētahi tohu 0.25 mL he pūtāhui mō te tika ki tētahi atu mati ā-ira.

Ko te tuhinga kei raro nei he hoahoa whakamārama taketake, ehara i te whakaahua, i te tiwhikete whakatikatika ine rānei. Kua whakaaturia tōna wai kia āhua pūataata, kia kitea ai te mata.

E hāngai ana te wāhi raro rawa o te mata wai kōpiko whakaroto e kitea ana ki te 0.5 mL. E whakaatu ana ngā tātaitanga e rua he aha e rerekē ai ngā rahinga kei roto i te rōrahi kotahi. He tauira ine ēnei, ehara i te horopeta e taunakitia ana.

Pānuitia te tauine i mua i te whakakī

Tautuhia ngā waeine i te tuatahi. Ko tētahi tohu kua tapaina ki te mL e ine ana i te rōrahi. Ko tētahi tohu kua tapaina ki te mg ka whakaahua i te rahinga mō te kukū motuhake anake i hoahoatia ai taua taputapu. Kāore tētahi ngongo karāhe kāore he tohu e whakarato ana i tētahi pānuitanga ā-tau pono mō te rōrahi.

Whai muri, tirohia te raupapa me ngā mokowā. I te tauine kua whakaahuatia, e tata ake ana te 0.25 mL ki te pito, kei runga ake te 0.5 mL, ā, kei runga ake anō te 1 mL. Ko te rerekētanga ā-tau mai i te 0.5 ki te 1 mL he rearua o te rerekētanga mai i te 0.25 ki te 0.5 mL. Kaua e whakapae he ōrite te pikinga e tohuhia ana e ia takirua tau tāngia e pātata ana.

Mēnā he tohu iti kei waenganui i ngā tohu o tētahi atu taputapu, whakatauria te uara o aua tohu mā ngā tohu pito kua tapaina. Hei tauira, ko ngā wāhanga ōrite e rima i waenganui i te 0.5 me te 1 mL e tohu ana i te 0.1 mL mō ia wāhanga: ko te rerekētanga, 0.5 mL, ka whakawehea ki te rima. Tatauria ngā mokowā, kaua te maha o ngā rārangi e kitea ana. Kāore taua tauira e tohu ana kei te pūwhakataka e tukuna ana me te hua aua wehenga tāpiri.

Whakatakotoria te mata wai ki te taumata o ngā karu

Whāia ngā tohutohu whakakī o te taputapu. Mō tētahi pūwhakataka whai pōro rapa noa, pēhia te pōro rapa i mua i te rukunga o te pito, kātahi ka āta tuku kia kumea te wai ki roto i te ngongo. Kaua e tukua te wai kia uru ki te pōro rapa. Ko ngā āputa hau e kitea ana i roto i te tīwae e inea ana ka noho ki ngā wāhi me noho te wai; kumea anō he wai, kaua e whakaae ki tētahi pānuitanga e kī ana i ngā mirumiru.

Puritia te ngongo kia tū poutū, ā, whakatakotoria te tohu e hāngai ana ki te taumata o ngā karu. Mā te titiro whakararo mai i runga, whakarunga rānei mai i raro, ka āhua neke te mata ki tētahi atu wāhi i runga i te tauine. Ko te ingoa o tēnei hapa tirohanga ko te parallax.

Ko te mata wai kōpiko te meniscus. Mō tētahi mata kōpiko whakaroto e kitea ana, ka whakamahia tōna wāhi raro rawa i waenganui mō te pānuitanga tikanga noa, e whakaaturia ana. E whakamārama ana ngā aratohu a NIST mō te pānui i te mata wai kōpiko i te whakatūtaki ki te taumata o ngā karu, me te take me hāngai te tikanga pānui ki te whakatikatika ine. Ka matapaki hoki i ngā uauatanga o ngā wai puatakore.

Nā te pōuri o te kahurangi metilēni, ka uaua pea te wehewehe i taua mata. Whakapai ake i te whakamāramatanga, ā, whakamahia he papamuri mania, he tae rerekē. Mēnā ka huna tonu te wāhi tohutoro kua whakaritea, rapua ngā tohutohu e hāngai pū ana ki te taputapu, tētahi atu taputapu ine e tika ana rānei. Kaua e whakakapi noa i te tapa raro e kore e kitea ki te tapa runga, me te whakapae he ōrite te hua.

Hurihia te rōrahi kua inea ki te rahinga

Ko te tātaitanga:

Rahinga ki te mg = rōrahi kua inea ki te mL × kukū ki te mg/mL.

Mō tētahi ōrau taumaha mō ia rōrahi, ko te tikanga o te 1% w/v he 1 g kei roto i te 100 mL o te wairewa whakamutunga. Nā te mea he 1,000 mg te 1 g, he 10 mg/mL tēnei. Kāore e oti tētahi ōrau mēnā kāore tōna pūtake e tohua: he rerekē ngā whakamāramatanga o te taumaha mō ia taumaha me te taumaha mō ia rōrahi.

Ko te rārangi tuawhā he wairewa whakatairite pohewa, ehara i te kerēme mō tētahi atu hua Blupreme. Kia mahara he ōrite te papatipu kei roto i te 0.25 mL o te kukū tuatahi me te 0.5 mL o te kukū tuarua. Engari, mō tētahi pānuitanga ōrite o te 0.5 mL, he rearua te rahinga matū kei te 10 mg/mL i tō te 5 mg/mL.

Ka mahia ēnei tātaitanga waeine e te pūhuri kukū. Me whai mōhiohio anō mō te āhua rāpoi ngota me te pūtake papatipu mō te kukū ā-mōra taiwhanga; ka kōrerotia ēnei i te pūtātai kukū ā-mōra mō te kahurangi metilēni.

He aha i kore ai e pono ngā ara poto o te tatau pata me te “pūwhakataka kī”

Ko te pata he wāhanga wai kua wehe mai i tētahi pito, ehara i te rōrahi kua whakatikahia te ine e ōrite ana i ngā wā katoa. I whakatairite tētahi rangahau a Brown me ōna hoa mō ngā pūwhakataka rongoā ā-waha i te tuku wai i raro i ngā tikanga whakahaere o te taiwhanga me te whakamahinga a ngā tūao. Nā te tītaha o ngā pūwhakataka i whakamātauria ki te 45 nekehanga mai i te tū poutū, ka iti iho ngā rōrahi i tukuna, ka nui ake hoki te rerekētanga. He rangahau tuku wai tēnei me ētahi atu wai rongoā, ehara i te whakamātautau kahurangi metilēni.

Nō reira, kāore e taea te whakawhiti noa i tētahi uara pata mō ia miririta kua whakatauria mō tētahi taputapu me tētahi wai ki tētahi atu. Waihoki, kāore tētahi pēhinga kotahi o te pōro rapa e tautuhi ana i te rōrahi o tētahi “pūwhakataka kī”. Pānuitia te tohu i tino tae atu ai te wai. Kaua e whakakapi i te ine mā te tatau pata ina whakapuakina te inenga e hiahiatia ana ki te mL.

Tiakina te tikanga o te inenga

Tuhia 0.5 mL, me te kore kei mua. E whakanui ana ngā taunakitanga a FDA mō te ine rongoā wai i te whakahāngai i ngā waeine o te tapanga me te taputapu, me te whakamahi i ngā kore ki mua mō ngā rahinga iti iho i te kotahi. Kāore ēnei mātāpono ine whānui e whakaū ana i tētahi whakamahinga hauora mō te wairewa hoko ā-toa.

Mēnā he iti iho te rōrahi kua whakaritea i te tohu raro rawa, he nui ake i te kaha pupuri, e hiahia ana rānei ki ngā wehenga iti ake i ērā kei te taputapu, kōwhiria he taputapu e tika ana mō taua inenga i te taha o te mātanga, o te taiwhanga rānei e hāngai ana. Kaua e whakatau tata i tētahi hautanga kāore he tohu, kātahi ka pūrongo hei inenga tino tika. Whāia ngā tohutohu tuku wai me te horoi a te kaihanga; kaua e waihanga noa i ētahi horoinga, whakaheke wai tāpiri rānei hei whakahoki mai i te wai e toe ana.

Mō ngā pātai hauora, ka whakamārama te aratohu motuhake mō ngā waeine horopeta kahurangi metilēni he aha te rahinga kua tātaihia mai i tētahi tapanga pounamu e kore ai e noho hei taunakitanga maimoatanga. Ko te ine tika e whakautu ana e hia kei roto. Me whai whakatau haumanu motuhake hei kōwhiri i tētahi horopeta mā te tangata.
