Beer-Lambert law कैलकुलेटर

Absorbance, molar absorptivity, concentration aur path length se Beer-Lambert ki missing variable nikaliye, jahan concentration aur optical path ki units saaf tarah se handle hoti hain taki spectrophotometry ka kaam seedha rahe.

यह कैसे काम करता है

सूत्र

A = \varepsilon \cdot c \cdot l

c = \frac{A}{\varepsilon \cdot l}

l = \frac{A}{\varepsilon \cdot c}

\varepsilon = \frac{A}{c \cdot l}

T = 10^{-A}

\%T = 100 \cdot T

चर, चिह्न और इकाइयाँ

$A$: Absorbance
$\varepsilon$: Molar absorptivity(L/mol/cm)
$c$: Concentration(M, mM, uM)
$l$: Path length(cm, mm)
$T$: Transmittance fraction
$\%T$: Percent transmittance(%)

गणना विधि समझाई गई

Missing variable chuniye, Beer-Lambert ki baaki teen values dijiye, aur units ko explicit rakhiye. Calculator har baar A = εcl ka ek rearranged form solve karta hai aur phir us case ki absorbance se transmittance nikalta hai.

Solve karne se pehle units normalize hoti hain: concentration ko molarity (M) me convert kiya jata hai, path length ko centimeters me, aur molar absorptivity ko user-supplied L/mol/cm value maana jata hai. Uske baad answer wahi concentration ya path-length unit me wapas dikhaya jata hai jo aapne select ki. Ye page jaan-bujhkar narrow rakha gaya hai: ye extinction coefficient estimate nahin karta, calibration curve nahin banata, aur dilution planning nahin karta.

अक्सर पूछे जाने वाले प्रश्न

Ye equation kin assumptions par chalti hai?

Beer-Lambert tabhi meaningful hota hai jab absorbance, molar absorptivity, concentration aur path length sab ek hi assay context se aaye hon. Wavelength, solvent ya buffer, blanking method aur path-length assumption ko match karke hi result par bharosa kijiye.

Path length itna important kyon hai?

Is model me absorbance, path length ke proportional hoti hai. Agar concentration aur molar absorptivity same rahein, to path length double karne par A bhi double hota hai, aur aadha karne par A bhi aadha hota hai.

Yahan transmittance ka kya matlab hai?

Transmittance absorbance se derive hoti hai: T = 10^-A aur %T = 100 × T. Jitni absorbance zyada hogi, utni hi kam roshni sample ke through jayegi.

Kab dilute karna ya reading repeat karna better hota hai?

Agar aapki method ke hisaab se absorbance bahut high lag rahi hai, to optical read kam clean ho sakta hai ya assay ke calibrated range se bahar ja sakta hai. Protocol ya calibration check kijiye, aur agar agla kaam diluted rerun banana hai to Solution Dilution calculator use kijiye.

Kya is calculator me compounds ya normal ranges built in hain?

Nahin. Isme substances, extinction coefficients, calibration tables ya normal ranges preload nahin kiye gaye. Result ki quality aapke diye hue assay values par depend karti hai.
