Calculate the content c in grams per litre or the content c′ in per cent m/m of a dissolved substance using the following formulae: α = angle of rotation in degrees read at 20 ± 0.5°C; l = length in decimetres of the polarimeter tube; ρ20 = density at 20 °C in grams per . A new section on Qualification of Polarimeters was added. The reported optical rotation using visual polarimeters and replicate measurements has been removed. Comments on the chapter can be submitted from now on. The comment deadline is July 31, 2021. The draft chapter USP <781> Optical Rotation can be viewed here.The values for refractive index given in this Pharmacopeia are for the D line of sodium (doublet at 589.0 nm and 589.6 nm). Most instruments available are designed for use with white light but are calibrated to give the refractive index in terms of the D line of sodium light.
4.3. Instrument Calibration: 4.3.1. Perform the necessary calibration procedures as specified by the manufacturer or the laboratory’s standard operating procedures. This involves calibrating the Polarimeter using standard solutions of known optical rotation and adjusting the instrument accordingly. 4.3.2. Different solutions cut off a different wavelengths: whereas EP 2.2.25 formerly named just one stray light reference, potassium chloride solution, both standards now list several references covering wavelengths from 190 nm to 400 nm; the measured absorbance at the recommended wavelength must exceed the stated value. Note that USP <857> now .reference to a layer 100 mm thick of a solution containing 1 g of the substance per mL. where a is the observed rotation, l is the length of the observed layer in mm, c is the number of g of substance contained in 100 . (the latter value having been established by calibration of the polarimeter scale with suitable standards),retardations measured with this polarimeter. 6.1.3 Verification of Quarter-Wave Plate, Q—Using a pola-rimeter equipped with a Babinet compensator, measure the retardation of the quarter-wave plate. The retardation must be 141 6 5 nm. 6.2 Procedure B—Calibration of Polarimeter Using a Cali-brated Retarder:

USP and EP require measurement of optical rotation using the Sodium D .4.1 Verification and calibration of polarimeters are accomplished using the following procedures: 4.1.1 Procedure A: (Verification) —Measure individual components and their orientation to ensure that the requirements of Test Methods F218, C148, and C978 are satisfied.%PDF-1.4 %âãÏÓ 2 0 obj >/Border[0 0 0]/C[0 0 1]>> endobj 5 0 obj >/Border[0 0 0]/C[0 0 1]>> endobj 7 0 obj >/Border[0 0 0]/C[0 0 1]>> endobj 1 0 obj > endobj 4 0 obj > endobj 8 0 obj > endobj 6 0 obj > endobj 3 0 obj > endobj 9 0 obj > endobj 10 0 obj >stream xœ+ä î| endstream endobj 11 0 obj >stream xœ“Qo›0 .ßù ÷1• ØÆ`ì§Ñ ÓšR Ò *¡”@Ç–@ æ!ÿ¾¦K»® i .
Verifying the operation and per formance of an analytical instrument is a critical par t of a robust quality management system and is r equired in a current good manufacturing practice (GMP) environment. . Calibration is about metr ology. Calibration is that par t of qualication r elating to measurement integrity of the ordinate response and .the client regarding uncertainty of calibration of the instrument [4]. If selection of the weights for calibration of the balance is based on nominal value of the mass of the standard weight used for calibration, then the MPE of the weight (Table 2) shall not be greater than the MPE of the balance divided by 3: MPE Weight ≤ MPE balance 33. Polarimeters and the calibration The polarization state of a wave incident on a polarizer in front of the first amplification stage of a receiver can be described by two circular components. Following Kraus (1966), these components can be expressed as: where r,l represent the electric vector amplitude of each of the circularly polarized components, and their relative phase.
