NIST Traceable Calibration Standards
Rudolph Research utilizes the highest calibration standards in the laboratory instruments industry. To view our full American Association for Laboratory Accreditation (A2LA)CERT#7528.01 and Scope of Accreditation, please visit our Quality page.
NIST ve ICUMSA Standartlarına göre üretilmiştir
Rudolph Research Analytical Quartz Control Plates provide a permanent calibration standard for polarimeters and saccharimeters. Every Rudolph calibration standard is manufactured using extremely stable crystalline quartz which is manufactured and polished to specific planeness, parallelism, purity and axis standards. These standards meet or exceed the specifications outlined on Page 61 of the National Institute for Standards and Technology (NIST) Circular C440 or as laid down by the International Commission for Uniform Methods of Sugar Analysis (ICUMSA). Each Quartz Plate comes complete with a label showing calibration at 12 different wavelengths (Picture G), a protective box and a NIST Traceable Certificate.

Many rotations are available but generally available stock rotations are listed on back page. Quartz Plates come in single and 3 Rotation Quartz Plates. Single Quartz Plates have a single rotation value at each wavelength and are calibrated in ˚Arc (Optical Rotation) and ˚ISS/˚Z (Sugar Degrees). 3 Rotation Quartz Plates are also calibrated in ˚Arc and ˚ISS/˚Z, but have three rotation values at each wavelength(Picture F). This is possible because each plate is made up of one left or levo turning Quartz Plate (i.e. –10˚ Arc) and one right or dextro turning plate (i.e. +12˚ Arc) which may be used separately or together for a combined rotation of 2˚Arc (12˚–10˚). Every Rudolph Research Analytical Quartz Plate is manufactured to a reported uncertainty of ±0.002° Arc at 589. Please contact the factory for the Quartz Plate that is best suited for your needs.

Kuvars Kontrol Plakalarının Yeniden Kalibrasyonu
Ne NIST ne de ICUMSA Polarimetre Kuvars Kontrol Plakası Yeniden Kalibrasyon sıklığı için kılavuzlar sağlamamaktadır. Kuvars zaman içinde optik olarak kararlı olduğundan, optik rotasyonundaki değişiklikler optik stresin veya fiziksel kullanımdan kaynaklanan yüzey çiziklerinin sonucudur. Bu nedenle, Rudolph Research Analytical'ın görüşüne göre bir Kuvars Kalibrasyon Standardının her iki ila üç yılda bir yeniden kalibre edilmesi yeterlidir. Kuvars aksesuar plakasının yeniden kalibrasyonu ile ilgili daha fazla yardım için info@rudolphresearch.com adresine bir e-posta gönderin veya +1-973-584-1558 numaralı telefondan fabrikamızı arayın.
Her Kuvars Kontrol Plakası Rudolph Research Analytical tarafından kalibre edilir ve Ulusal Standartlar ve Teknoloji Enstitüsü(NIST) tarafından izlenebilir.
