Hanna Instruments \u2018, Handheld Colourimeter Checker\u00ae HC proizvodi pru\u017eaju nenadma\u0161nu kombinaciju ta\u010dnosti, kvaliteta i pristupa\u010dne cene.<\/p>\n

Iako su Checkeri vrlo jednostavni za upotrebu \u2013 kao i svaki nau\u010dni instrument, male gre\u0161ke mogu negativno uticati na va\u0161e o\u010ditanje.<\/p>\n

Iz tog razloga smo sastavili ovaj kratki vodi\u010d kroz najbolje prakse upotrebe Checkera, kako bi u budu\u0107nosti izbegli sve gubljenje vremene i frustracije vezane za gre\u0161ke prilikom merenja.<\/p>\n

<\/p>\n

1. Uvek koristite \u010diste kivete<\/h2>\n

Za\u0161to:<\/strong>\u00a0Proizvodi iz linije Hanna Checker su kolorimetri, \u0161to zna\u010di da koriste izvor svetlosti \u2013 poput LED ili Volframove lampe \u2013 sa filterom i detektorom svetlosti za odre\u0111ivanje apsorbance i koncentracije jona. Buduc\u0301i da Checkeri zasnovaju merenja na opti\u010dkim podacima, va\u017eno je da svetlost ne ometaju otisci prstiju, ogrebotine, prljav\u0161tine ili mehuric\u0301a vazduha u Va\u0161im kivetama.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Koristite mikrofiber krpu da obri\u0161ete kivete spolja. Za otklanjanje mehuri\u0107a, lagano \u201ckucnite\u201d kivetu pre postavljanja u Checker.<\/p>\n

2. Koristite odvojene pipete<\/h2>\n

<\/p>\n

Za\u0161to:<\/strong>\u00a0Upotreba iste pipete za slanu i slatku vodu mo\u017ee da kontaminira uzorak slatke vode, \u0161to dovodi do pojave neta\u010dnosti, jer ne\u0161to soli mo\u017ee ostati unutar pipete.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Ozna\u010dite \u0161priceve ili pipete koje koristite kako ih ne biste pome\u0161ali.<\/p>\n

3. Postavite kivetu svaki put u istu poziciju<\/h2>\n

Za\u0161to:<\/strong>\u00a0Kada koristite Checker, va\u017eno je da du\u017eina opti\u010dke putanje bude uvek ista kako bi se obezbedilo stalno i ta\u010dno o\u010ditavanje.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Stavite malu oznaku na poklopac ili vrh \u010da\u0161e kako biste pomogli da se indeksira polo\u017eaj kivete u ure\u0111aju.<\/p>\n

4. Ne dozvolite da reagensi \u201cle\u017ee\u201d u kiveti<\/h2>\n

Za\u0161to:<\/strong>\u00a0Ukoliko pustite da uzorak pome\u0161an sa reagensima predugo \u201cle\u017ei\u201d u kiveti mo\u017ee da oboji \u010da\u0161u. To \u0107e uticati na apsorbancu kako svetlost prolazi kroz staklo, rezultiraju\u0107i lo\u0161im o\u010ditavanjima.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Uvek praznite i ispirajte kivete nakon kori\u0161\u0107enja. \u0160to nas dovodi do slede\u0107e ta\u010dke\u2026<\/p>\n

5. \u010cistite kivete sa destilovanom ili dejonizovanom vodom<\/h2>\n

Za\u0161to:<\/strong>\u00a0Pre nego \u0161to se obavi novi test, kivete moraju biti oslobo\u0111ene moguc\u0301ih kontaminanata. Ispiranje vodom iz akvarijuma mo\u017ee nakon ispitivanja ostaviti zaostali materijal. Kivete tako\u0111e treba da se potpuno osu\u0161e na vazduhu nakon ispiranja kako bi se spre\u010dilo ne\u017eeljeno razbla\u017eivanje uzorka prilikom sledec\u0301eg ispitivanja.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Uvek ispraznite i isperite kivete destilovanom ili deionizivanom vodom nakon ispitivanja. Kada sme\u0161tate kivetu natrag u pakovanje, obavezno skinite poklopac.<\/p>\n

6. Proverite reagense<\/h2>\n

<\/p>\n

Za\u0161to:<\/strong>\u00a0Upotreba reagenesa sa isteklim rokom trajanja daje neta\u010dne rezultate.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Stvorite naviku da proveravate pakovanja reagenasa pre upotrebe. Za najbolje rezultate, uverite se da skladi\u0161tite reagense na hladnom, suvom mestu kako bi se izbegle dramati\u010dne temperaturne promene. Velike promene u temperaturi i vla\u017enosti mo\u017ee o\u0161tetiti reagense.<\/p>\n

7. U potpunosti zatvorite poklopac Checkera<\/h2>\n

<\/p>\n

Za\u0161to:<\/strong>\u00a0Alternativni izvor svetlosti usled otvorenog Checkera \u0107e ometati o\u010ditanja \u010dine\u0107i ih neta\u010dnima. Checker je dizajniran da koristi fiksni izvor svetlosti \u2013 poput LED ili volframove lampe \u2013 sa filterom i detektorom osetljivosti na svetlost za odre\u0111ivanje apsorbance i koncentracije jona.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Pre merenja pritisnite dodatno poklopac Checkera uveravaju\u0107i se da je u potpunosti zatvoren.<\/p>\n

8. Presecite kesice reagensa na ta\u010dno ozna\u010denom mestu<\/h2>\n

Za\u0161to:<\/strong>\u00a0Se\u010denje paketa du\u017e donjeg desnog ugla, ka gornjem levom uglu, napravi\u0107e levak koji omoguc\u0301ava lak\u0161e sipanje reagensa u kivetu. Nema prosipanja reagenasa, nema ni problema!<\/p>\n

Re\u0161enje:<\/strong>\u00a0Pre otvaranja kesice sa reagensima, protesite je tako da se uverite da nema zaostalog reagensa u \u0107o\u0161ku koji se\u010dete. Nakon toga upotrebite makaze da otvorite kesicu na ta\u010dno ozna\u010denom mestu.<\/p>\n

9- Validirajte Checker sa kalibracionim setom<\/h2>\n

<\/p>\n

Za\u0161to:<\/strong>\u00a0Kada niste sigurni kakva o\u010ditanja mo\u017eete o\u010dekivati od nove vrste uzoraka ili kada dobijete neobi\u010dne vrednost, va\u017eno je da validirate fabri\u010dku kalibraciju Checker-a.<\/p>\n

Re\u0161enje:<\/strong>\u00a0Setovi za validaciju imaju poznatu koncentraciju parametra koji se meri i omoguc\u0301uju Vam da brzo potvrdite da Checker radi ispravno
\nOvi visokokvalitetni standardi dolaze sa sertifikatom o analizi koji uklju\u010duje broj partije, referentne vrednosti i datum isteka kako bi se obezbedila sledljivost prilikom sertifikacije Checker-a.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
