水質(zhì)分析儀在使用過程中應(yīng)該注意以下問題:

1、系統(tǒng)全密閉問題。卡爾-費(fèi)休試劑液路部分連接一定要緊固，從試劑瓶到計(jì)量泵再到反應(yīng)池，否則發(fā)生試劑泄漏將直接影響測試結(jié)果。其不密閉的另一個(gè)問題是測試時(shí)由于卡爾費(fèi)休試劑在試驗(yàn)中吸收空氣水分，會導(dǎo)致滴定終點(diǎn)延遲。

2、取樣的準(zhǔn)確問題。在標(biāo)定卡爾-費(fèi)休試劑時(shí)需要取用10mg水，盡量使用10ul取樣器，這樣不但準(zhǔn)確、速度快，還能夠防止水滴粘附。同樣地，取用甲醇試劑、乙酯也有類似的問題，取放完畢后應(yīng)注意盡量縮短反應(yīng)池打開的時(shí)間。

3、磁性攪拌速度調(diào)整。在反應(yīng)池中，因?yàn)榈味ㄔ噭┘尤霑r(shí)在局部，與電極不在一處，因此攪拌速度以快到不形成湍流為止，這樣可以快達(dá)到終點(diǎn)。

4、滴定速度設(shè)定應(yīng)先快后慢。滴定時(shí)先快速以盡量縮短試驗(yàn)時(shí)間，而在接近終點(diǎn)時(shí)應(yīng)變慢，這樣可提高計(jì)量精確度。

5、當(dāng)日試驗(yàn)完畢后，一定要排空系統(tǒng)中的卡爾-費(fèi)休試劑，然后用甲醇清洗干凈，千萬不能用水清洗系統(tǒng)，因?yàn)槠洳蝗菀讚]發(fā)，將造成下次試驗(yàn)時(shí)卡爾-費(fèi)休試劑標(biāo)定不實(shí)。

6、水分測定儀應(yīng)該遠(yuǎn)離強(qiáng)磁場，避免工作時(shí)電子顯示跳動，出現(xiàn)不正常現(xiàn)象。手動的水分測定儀，因?yàn)楸仨毷褂貌Ａё詣拥味ü苡?jì)量卡爾-費(fèi)休試劑和甲醇溶劑，而玻璃滴定管本身因?yàn)槠胶鈮毫Φ年P(guān)系，又必須與外界接通。

7、系統(tǒng)盡量密閉。手動的水分測定儀需要在吸球管路和玻璃滴定管上口加接填充干燥劑的U型管，以便減少空氣水分對測試結(jié)果的干擾。在空氣相對濕度大于70%的環(huán)境下，應(yīng)盡量不安排水分測試。

8、在調(diào)整滴定管的滴定速度時(shí)，調(diào)整到1滴/秒。滴定速度太快將導(dǎo)致到達(dá)終點(diǎn)時(shí)產(chǎn)生的延時(shí)誤差較大;而滴定速度太慢則會延長測試的過程，上述干擾容易導(dǎo)致遲遲不到達(dá)終點(diǎn)。
