الأسئلة الشائعة حول مقياس الطيف الضوئي للأشعة المرئية وفوق البنفسجية

س1: What are the primary advantages of a double-beam optical system on the BRT-3200UV?

أ: A double-beam optical layout continuously splits light between a reference path and a sample path. This design compensates for light source fluctuations and environmental drift in real time, delivering higher baseline stability, accuracy, and reproducibility during long spectral scans.

Q2: Does the BRT-3200UV require manual alignment when replacing lamps?

أ: لا. The BRT-3200UV features socket-type light sources (tungsten halogen and imported deuterium lamps) that allow quick plug-and-play replacement without complex optical alignment.

س3: What analytical features does the standard Mapada software offer?

أ: The standard analysis software supports GLP self-identification, continuous full-spectrum scanning, quantitative curve fitting, time-course enzyme kinetics (ΔA/Δt), اختبار الأطوال الموجية المتعددة, وفحوصات الحمض النووي / البروتين (260/280 نانومتر) with standardized report generation.
