Malvern Panalytical Zeta Reference Sample NTA4096

NTA4096 is a Malvern Panalytical Zeta Potential standard for use with NanoSight NTA instruments to check zeta-potential measurement performance. The sample is derived from the Malvern Zeta Potential transfer standard (DTS1235) and is supplied with a diluent and measurement protocol for use on NanoSight NS500 zeta-enabled instruments running NTA software (version 2.3 or later). The standard is intended to verify instrument performance and to produce high-resolution, particle-by-particle zeta potential distributions for routine performance checks.

Key Features:

• Product code: NTA4096
• Derived from Malvern Zeta Potential transfer standard DTS1235
• Prepared as a supplied standard with accompanying diluent; use a 4-fold dilution prior to measurement
• Applicable to NanoSight NS500 zeta-enabled instruments with NTA software v2.3 or later
• Measurement checks include voltage response at 24 V and focus/brightness verification at five pre-calibrated positions
• Accuracy: modal zeta potential within ±10% of the value supplied with the sample and coefficient of variance under 5%

Advantages:

• Provides a manufacturer-derived reference material to verify zeta-potential instrument performance
• Enables high-resolution, particle-by-particle zeta potential distributions for detailed performance assessment
• Includes a defined measurement protocol (dilution, electrode and focus checks, voltage test) to standardize routine verification
• Designed for regular (for example monthly) checks to document consistent instrument operation
