Chemiluminescent NO/NOX Cov kws tshuaj ntsuam xyuas
Nova Model 300 CLD Cov kws tshuaj ntsuam xyuas yog tsim los ntsuas tas li ntsuas tag nrho cov concentration ntawm oxides ntawm nitrogen hauv cov qauv gaseous. Cov txheej txheem yog raws li cov chemiluminescent Cov tshuaj tiv thaiv ntawm ozone thiab nitric oxide (NO) los tsim nitrogen dioxide (NO2) thiab oxygen.
Kuj paub, NOx analyzer ua haujlwm li cas?
Chemiluminescence ua haujlwm ntawm lub hauv paus ntsiab lus uas Nitric Oxide (NO) thiab Ozone (O3) react los tsim lub zog uas luminesces. Lub teeb pom kev tuaj yeem ntsuas thiab sib raug rau qhov concentration ntawm NO siv lub raj photomultiplier. NOx yog sib npaug rau NO + NO2.
Qhov thib ob, koj ua li cas kuaj rau chemiluminescence? 5.2 Chemiluminescent Detection . Chemiluminescence yog tshuaj lom neeg cov tshuaj tiv thaiv nyob rau hauv uas cov tshuaj substrate yog catalyzed los ntawm ib tug enzyme, xws li AP los yog HRP, thiab tsim teeb pom kev zoo. Lub teeb liab tuaj yeem ntes tau ntawm X-ray zaj duab xis, lossis los ntawm cov khoom siv sib txuas (CCD) duab.
Tom qab ntawd, lo lus nug yog, siv chemiluminescence li cas?
Kev siv tshuaj lom neeg. Chemiluminescence tau siv los ntawm cov kws tshawb fawb forensic los daws kev ua txhaum cai. Hauv qhov no, lawv siv luminol thiab hydrogen peroxide. Cov hlau los ntawm cov ntshav ua raws li cov catalyst thiab reacts nrog luminol thiab hydrogen peroxide los tsim lub teeb xiav rau li 30 vib nas this.
Peb piv txwv ntawm chemiluminescence yog dab tsi?
Enzyme tiv thaiv xws li phenols, napthols, aromatic amines, los yog benzothiazoles yog ntxiv rau cov tshuaj tiv thaiv kom khaws cov enzyme thiab txhim kho lub teeb tso zis ntau tshaj li ob peb feeb. Vim li no cov molecules no hu ua "enhancers". Lwm cov piv txwv chemiluminescence yog cov luminol nrog hydrogen peroxide.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Lub luag haujlwm ntawm lub cell membrane yog dab tsi thaum lub sijhawm thauj mus los?
Lub cell membrane yog xaiv permeable rau ions thiab organic molecules thiab tswj kev txav ntawm cov khoom hauv thiab tawm ntawm lub hlwb. Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog los tiv thaiv lub cell ntawm nws ib puag ncig. Nws muaj phospholipid bilayer nrog embedded proteins
Lub zog zoo li cas yog lub teeb lub zog hloov dua siab tshiab kom lub tshuab xam zauv ua haujlwm?
Kab nyob rau sab saum toj ntawm lub tshuab xam zauv. Ua li cas lub zog yog lub teeb lub zog hloov dua siab tshiab kom lub tshuab xam zauv ua haujlwm? Lawv hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob. zaub mov
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
