Portable Ultraviolet Meter

Hangzhou Qiwei Instrument Co., Ltd. yog ib qho ntawm cov tuam txhab ua lag luam thiab cov chaw muag khoom ntawm portable ultraviolet meter hauv Suav teb. Nrog ib pab neeg tsim khoom, peb muaj peev xwm ua tau raws li qhov xav tau ntawm feem ntau ntawm peb cov neeg siv khoom. Txais tos rau kev lag luam wholesale bulk portable ultraviolet meter hauv Tshuag ntawm no los ntawm peb lub hoobkas. Peb kuj txais customized txiav txim.

Taw qhia

Lub portable ultraviole meter ntawm lub ultraviolet analyzer yog tsim los ntawm quartz iav ultraviolet teeb lub raj thiab lim. Lub wavelengths ntawm ob pawg ntawm lub teeb qhov chaw yog 254 nm thiab 365 nm, feem. Lub teeb ci tuaj yeem siv rau hauv kev sim los ntawm kev lim cov xim ntawm lub lim, thiab ob lub teeb ci tuaj yeem siv ib leeg lossis sib xyaw tib lub sijhawm.

Txoj Cai

Ultraviolet analyzer ua haujlwm raws li qhov nqus ntawm ultraviolet lub teeb los ntawm cov khoom siv lossis cov yam ntxwv ntawm fluorescence tsim tom qab excitation. Cov teeb meem zoo ib yam hauv lub xeev hauv av yuav nqus lub zog thiab dhia mus rau lub xeev zoo siab tom qab raug irradiated los ntawm ultraviolet lub teeb ntawm ib lub wavelength tshwj xeeb. Thaum cov molecule zoo siab rov qab los rau hauv av, nws yuav tso tawm ntau lub zog nyob rau hauv daim ntawv ntawm emission fluorescence. Vim muaj cov qauv molecular sib txawv ntawm cov khoom sib txawv, lub wavelength thiab kev siv ntawm fluorescence emission kuj txawv. Cov cuab yeej ua tau zoo thiab ntau qhov kev soj ntsuam ntawm cov khoom los ntawm kev kuaj xyuas cov fluorescence (wavelength, siv) tawm los ntawm cov qauv los yog ntsuas qhov℃ntawm attenuation ntawm lub teeb ultraviolet tom qab dhau los ntawm cov qauv (absorbance).

1. Cov cuab yeej no tau siv dav hauv ntau qhov chaw rau kev tsom xam fluorescence thiab kev txheeb xyuas cov khoom.

2. Nws tshawb pom cov khoom tseem ceeb xws li cov proteins thiab nucleotides hauv kev tshawb fawb tshawb fawb.

3. Hauv kev tsim tshuaj, nws tshuaj xyuas cov tshuaj fluorescent nrog rau cov tshuaj hormones, alkaloids, thiab cov vitamins, thiab txhawb nqa qhov chaw kuaj pom hauv nyias - txheej thiab ntawv chromatography.

4. Hauv kev lag luam tshuaj, nws txheeb xyuas cov khoom siv fluorescent, tshuaj ntxiv, dyes, txheej, cov khoom siv roj hmab, thiab cov khoom siv roj av.

5. Nws kuj tseem kuaj cov khoom siv textiles thiab cov khoom tiav, kuaj cov aflatoxins thiab cov khoom siv ntxiv hauv cov zaub mov, thiab pab pawg saib xyuas kev ruaj ntseg rau pej xeem hauv kev txheeb xyuas cov ntaub ntawv pov thawj, ntsuas ntiv tes, thiab sau ntawv pov thawj.

Cov cuab yeej muaj 254nm thiab 365nm UV teeb sib dhos nrog cov ntawv lim siab. Ib qho ua tau - nyob rau hauv fluorescent teeb muab illumination rau cov qauv tso rau ntawm TLC daim hlau. Cov qauv tag nrho yog qhov yooj yim, lub teeb yuag, thiab ruaj khov, nrog cov khoom sib hloov tau yooj yim rau kev saib xyuas yooj yim thiab kev pab lub neej ntev.
