Polarimetre - Kuvars Plaka Kalibrasyon Standartları
Rudolph Research endeavors to adhere to the highest know calibration standards in the laboratory instrument industry. To view our full Scope of Accreditation, please visit our Quality page.
Manufactured to ISO 17034 CRM | ISO/IEC 17025 | SI-Traceable | ICUMSA Methods
Rudolph Research Analytical Quartz Control Plates provide a stable reference for calibrating polarimeters and saccharimeters. Manufactured from high-quality crystalline quartz and precision processed for planeness, parallelism, purity, and axis orientation, these materials meet applicable specifications described in NIST Circular C440 and utilize ICUMSA-recognized methods where appropriate. Each plate includes calibration data at 11 wavelengths, a protective case, and documentation supporting metrological traceability to the SI, with measurements performed under ISO/IEC 17025 and produced in accordance with ISO 17034.
Kuvars Kalibrasyon Standardı Seçme
Kuvars Plaka Seçimi
Her rotasyon mevcuttur ancak genel olarak mevcut stok rotasyonları aşağıda listelenmiştir. Kuvars Plakaların tekli ve ikili versiyonları mevcuttur. Tekli Kuvars Plakalar her dalga boyunda tek bir rotasyon değerine sahiptir ve °Arc (Optik Rotasyon) ve °ISS/°Z (Şeker Derecesi) cinsinden kalibre edilir. Çift Plakalar da °Arc ve °ISS olarak kalibre edilir, ancak her dalga boyunda üç rotasyon değerine sahiptir. Bu mümkündür çünkü her plaka, 2° Ark (+12°-10°) kombine dönüş için ayrı ayrı veya birlikte kullanılabilen bir sol veya levo dönüşlü Kuvars Plakadan (yani -10° Ark) ve bir sağ veya dekstro dönüşlü plakadan (yani +12° Ark) oluşur. Her Rudolph Research Analitik Kuvars Plakası, 589'da ±0,002° Ark rapor edilen bir belirsizlikle üretilmektedir. İhtiyaçlarınıza en uygun Kuvars Aksesuar Plakası için lütfen fabrika ile iletişime geçin.

Kuvars Kontrol Plakalarının Yeniden Kalibrasyonu
Neither NIST nor ICUMSA provide guidelines for the frequency of Polarimeter Quartz Control Plate Recalibration. Since quartz is optically stable over time, changes in its optical rotation are the result of optical stress or surface scratches caused by physical handling. Therefore, it is the opinion of Rudolph Research Analytical that recalibration of a Quartz Calibration Standard every two to three years is satisfactory. For further assistance with quartz accessory plate recalibration, send an email to info@rudolphresearch.com, or call our factory at +1-973-584-1558.
Every Quartz Control Plate is calibrated by Rudolph Research Analytical and is traceable to the National Institute of Standards and Technology (NIST).
