- Description
- A particle size analysing instrument for use in laboratories. A light scattering instrument for the measurement of molecular weight and particle size in samples such as viruses and virus-like particles. This advance range is for the measurement of size, molecular weight, particle concentration and zeta potential of dispersed particles & molecules. Combines dynamic light scattering (DLS) and electrophoretic light scattering (ELS) systems including non-invasive back scatter and multi-angle dynamic light scattering (90° and 13°) giving a higher resolution view of the sample’s size distribution for critical measurements. The system includes max. 10mW HeNe laser (633nm) with high sensitivity APD detector. Size/molecular weight by DLS/SLS measured at 173-degrees using non-invasive back scatter, 90-degree DLS/SLS measurements also possible. Unique adaptive correlation for faster, reproducible, DLS measurements with no data loss. Incorporates multi-angle dynamic light scattering measurements for higher resolution DLS analysis and peak particle concentration analysis of samples <500nm. Zeta potential analysis incorporates M3-PALS and constant current zeta mode for measurement of zeta potential distributions and improved data quality in conductive media. The product also comes with ZS Xplorer analytical application software for data analysis. Deep Learning empowered data quality system for assessment of any size data quality issues, with clear advice on how to improve results.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect :– a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a)); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b)). General Interpretative Rules (GIRs): GIR 1 has been used to classify this product by the terms of heading 9027 - Instruments and apparatus for physical or chemical analysis (for example, polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus); instruments and apparatus for measuring or checking viscosity, porosity, expansion, surface tension or the like; instruments and apparatus for measuring or checking quantities of heat, sound or light (including exposure meters); microtomes. GIR 6 Has been used to classify the goods to subheading level 902750 - Other instruments and apparatus using optical radiation (UV, visible, IR). Also classified in accordance with:- Harmonized System Explanatory Notes (HSENs) to heading 9027
