The LDRP Reflectance Spectrometer is a portable instrument designed for industry field and laboratory investigations of chemical composition both of liquids and solids materials.
Technically, the LDRP is a multi-band photometer rather than a spectrometer, because it does not measure reflectance across a continuum of wavelengths. Rather, it measures reflectance in separate, non-overlapping ranges of wavelength. However, this distinction is not important for most applications.
The LDRP consists of lamps, a photo-detector, and an analyzer with display. These elements are arranged and coordinated with the sample and with each other to provide reproducible, easily interpretable results.
The Lamps are arranged so that their light passes are the same for each wavelength, being directed on to the surface of samples to be measured. And the diffused light after absorption by the samples was collected with focus system to the sensor.
In this configuration, the LDRP works best and most reproducibly with flat objects that have matte surfaces. Some shininess (as in most leaves) is acceptable.
Mirror-like surfaces will yield spurious readings.
For moderately rough surfaces, as small particles, the LDRP yields reasonable values for reflectance.
With very rough samples, light leaks can be a problem. Users can use the light protector sleeve to stop light leaks.
BD5-LDRP481X is special to samples. Users always need calibration for special applications. Internal memory capable of storing 8 separate calibrations. Use the calibrations provided by system, or create your own calibrations using the software function provided.
LDRP481X is designed for absorption bands detection, LDRS482X is designed for specific molecular absorption line analysis.

Application Details
The high OH absorption coefficient in the NIR Region makes BDTI Vis/NIR analyzers an ideal tool for accurate and flexible moisture analysis in raw materials, in-process and finished product. Using NIR as opposed to traditional, lengthy, and costly traditional moisture analysis, could save significant money and time.
Nutriment With growing pressure from the Food and Drug Administration on nutriments companies to standardize ingredients and ensure product purity, NIR technology has emerged as a cost-effective means for quality control in the manufacturing process of natural supplements. With the wider spectral range of LDRP and LDRS that other NIR instruments available, BDTI is taking 100% inspection of raw materials and finished products to a higher level by providing a vehicle for more reliable spectral data collection and seamless user-friendly interfaces to available chemo metric software. Professional food Nutrimental Analysis, enabling raw material testing quickly—at the dock, on the manufacturing floor, or where ever it is needed—positioning you to meet GMP and FDA requirements, quickly and easily.
