Varf\u00f6r det \u00e4r en bra id\u00e9 att anv\u00e4nda sj\u00e4lvmaskerande kyvetter…<\/p>\n\n

Den h\u00e4r artikeln f\u00f6rklarar varf\u00f6r det \u00e4r viktigt att anv\u00e4nda svarta v\u00e4ggar f\u00f6r arbete med l\u00e5g volym. Vi utf\u00f6rde detta experiment p\u00e5 en Varian Cary 500 f\u00f6r ett antal \u00e5r sedan f\u00f6r att visa detta. Experimentet:<\/p>\n\n

  1. Ta en l\u00e4mplig synlig och stabil kemikalie och bered en l\u00f6sning f\u00f6r att ge dig en maximal Absorbansm\u00e4tning p\u00e5 3+ Absorbans. I det h\u00e4r fallet anv\u00e4nde jag utsp\u00e4dd Starna Green, m\u00e4tt vid 428 nm, med en 1,0 nm SBW.<\/li>
  2. Kalla detta ‘100’ som en toppstandard – och sp\u00e4d seriellt f\u00f6r att producera ’75’, ’50’ respektive ’25’.<\/li>
  3. Anv\u00e4nd en klar v\u00e4ggcell VAOBS1<\/a> – fyll med vatten och nollst\u00e4ll Cary.<\/li>
  4. M\u00e4t \u00e4mnet igen och sedan varje standard i tur och ordning.<\/li>
  5. Upprepa 3 och 4 med en VAOBM1-cell med svart v\u00e4gg.<\/li>
  6. Rita och j\u00e4mf\u00f6r det linj\u00e4ra svaret ‘Beer-Lambert’!<\/li><\/ol>\n

    Hur de optiska egenskaperna hos cellerna p\u00e5verkar den kemiska m\u00e4tningen<\/strong><\/p>\n\n

    1. Anv\u00e4nda VAOBS1 klarv\u00e4ggscell- Med detta bevis tror jag inte att jag skulle vilja anv\u00e4nda den h\u00e4r typen av celler (utan n\u00e5gon maskering) f\u00f6r att m\u00e4ta mer \u00e4n 0,5 A?<\/p>\n\n

    2. Att anv\u00e4nda den svarta v\u00e4ggcellen VAOBM1<\/a> – vilken skillnad! Jag har \u00e5terst\u00e4llt min tilltro till min analytiska expertis – serien 0 – 75 (2,5 A) \u00e4r en perfekt rak linje (linj\u00e4ritet = 1). Linj\u00e4ritet till 3,3 (100) \u00e4r inte d\u00e5ligt heller vid 0,9993, men du b\u00f6rjar se str\u00f6ljusegenskaperna hos Cary 500-instrumentet vid det h\u00e4r laget.<\/p>\n\n
