Kalibrer<\/b><\/span><\/span>ing <\/b><\/span><\/span>af <\/b><\/span><\/span>pH-elektroden<\/b><\/span><\/span>. <\/span><\/p>\n
Det er kun n\u00f8dvendigt at kalibrere pH-elektroden en gang om dagen.<\/p>\n
N\u00e5r <\/span>man har<\/span> kalibreret pH-elektroden, <\/span>kan man<\/span> foretage <\/span>pH- og TA<\/b><\/span>-analyser<\/span>(syrem\u00e5ling)<\/span>.<\/span><\/p>\n
1. S\u00e6t pH-elektroden p\u00e5 apparatet.<\/p>\n
2. <\/span>T\u00e6nd appar<\/span>a<\/span>t<\/span>e<\/span>t.<\/span><\/p>\n
3. <\/span>Stil <\/span>ind <\/span> p\u00e5 Cal<\/span>–<\/span>mod<\/span>e\/<\/span>lys<\/span>.<\/span><\/p>\n
4. Skyl spidsen i destilleret vand <\/i>og dup forsigtigt vandet af med et stykke k\u00f8kkenrulle.<\/p>\n
5. <\/span>H<\/span>\u00e6ld op i <\/span>2 <\/span>skruel\u00e5g fra henholdsvis <\/span>4<\/span>,0<\/span>1<\/span> og <\/span>7<\/span>,0.<\/span><\/p>\n
6. Hold elektrode ned i l\u00e5get med 4,01 til cal lampen blinker og display er t\u00e6t p\u00e5 4,00,<\/p>\n
tryk <\/span>enter<\/i><\/span> og de<\/span>n<\/span> skriver <\/span>good cal<\/i><\/span>.<\/span><\/p>\n
7. Skyl med destilleret <\/i>vand <\/i>og dup forsigtigt med k\u00f8kkenrulle.<\/p>\n
8. Stik elektrode ned i 7,0 v\u00e6ske i l\u00e5get, stabiliserer sig p\u00e5 ca. 7, callampe blinker<\/i>, pres enter. <\/i>F\u00e6rdig <\/i><\/p>\n
9. S\u00e6t elektrodev\u00e6skebeholderen p\u00e5, hvis den ikke skal bruges mere den dag.<\/p>\n
SO2 analyse<\/b><\/span><\/p>\n
1. S\u00e6t SO<\/u><\/i>2<\/u><\/i><\/sub>–<\/u><\/i>elektrode<\/u><\/i>n<\/i> p\u00e5.<\/p>\n
2. <\/span>T\u00e6nd appar<\/span>a<\/span>t<\/span>e<\/span>t.<\/span><\/p>\n
3. <\/span>Stil ind <\/span>p\u00e5 <\/span>SO<\/span>2<\/span><\/sub> og tryk <\/span>enter <\/i><\/span>– d<\/i><\/span>er kommer lys i <\/span>proceed<\/i><\/span> og <\/span>0,0 i display.<\/i><\/span><\/p>\n
4. <\/span>Sug 5 ml SO<\/span>2<\/span><\/sub> titrant op i en spr\u00f8jte, <\/span>l\u00e6g den <\/span>p\u00e5 bordet.<\/span><\/p>\n
5. <\/span>Tag <\/span>25 ml <\/span>vin <\/span>i pipette og h\u00e6ld i <\/span>titreringsb\u00e6ger<\/span>,<\/span><\/p>\n
6. <\/span>H\u00e6ld en boble<\/span>(lille plastikpipette)<\/span> reaction solution<\/i><\/span> i b\u00e6geret og<\/span><\/p>\n
7. <\/span>en boble <\/span>acid solution<\/i><\/span> i ogs\u00e5..<\/span><\/p>\n
8. <\/span>S\u00e6t SO2-elektroen ned i vinblandingen og ryst\/cirkuler v\u00e6sken, mens der dryppes fra spr\u00f8jten. <\/span><\/p>\n
,<\/p>\n
 <\/p>\n
9. <\/span>N\u00e5r display er t\u00e6t p\u00e5 20, dryppes meget langsomt <\/span>evt. sm\u00e5 pauser<\/span>. N\u00e5r der er kommet mindst<\/span><\/p>\n
20 bi<\/span>p<\/span> er det slut.<\/span><\/p>\n
10. <\/span>Der af <\/span>af<\/span>l\u00e6ses hvor meget der er brugt fra spr\u00f8jten<\/span><\/p>\n
– <\/span>Fx: de<\/span>r<\/span> er brugt 1,5 ml fra spr\u00f8jten, det ganges med 20.<\/span><\/p>\n
1,5 ml x 20 = <\/span>30 mg\/l (30ppm SO<\/b><\/span>2<\/b><\/span><\/sub>)<\/b><\/span><\/p>\n
pH-m\u00e5ling af vin<\/span> <\/b><\/p>\n
1. 5 ml vin i b\u00e6ger<\/p>\n
2. pH mode-knap, rens\/skyl og t\u00f8r pH-elektrode<\/p>\n
3. S\u00e6t pH-elektrode<\/i> ned i vinen og afl\u00e6s display, n\u00e5r det har stabiliseret sig.<\/p>\n
TA-analyse <\/b>– syreindhold<\/b><\/span><\/p>\n
1. Indstil apparat p\u00e5 TA<\/p>\n
2. Ryst TA Titrant, tag 5 ml i spr\u00f8jte tryk\/ryst bobler ud, l\u00e6g den p\u00e5 bordet.<\/p>\n
3. 5 ml vin i lang pipette h\u00e6ld i b\u00e6ger, tils\u00e6t 15 ml destilleret vand.<\/p>\n
4. Skyl og t\u00f8r\/dup elektrode<\/p>\n
5. S\u00e6t pH-<\/i>elektroden<\/i> i vin\/vand-b\u00e6geret cirkuler v\u00e6sken og tils\u00e6t langsomt <\/span>Titrant fra spr\u00f8jten <\/span>–<\/span><\/p>\n
ekstra langsomt n\u00e5r display n\u00e6rmer sig 7.<\/p>\n
6. <\/span>N\u00e5r det er p\u00e5 8, bipper apparatet <\/span>og <\/span>analysen<\/span> f\u00e6rdig<\/span>.<\/span><\/p>\n
Man ser hvor meget der er brugt (mangler i spr\u00f8jten).<\/p>\n
Man ganger den brugte m\u00e6ngde med titrant 2 og har s\u00e5 resultatet.<\/p>\n
Fx: 3,5 ml x 2 = 7 <\/span>– – <\/span>dvs.: 7 gram syre pr liter<\/b><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
