Nanopartica nanoparticle analyzer sz 100

Manufactured by Horiba

The Nanopartica nanoparticle analyzer (SZ-100) is a compact instrument designed for the measurement of particle size and zeta potential of nanomaterials. It utilizes dynamic light scattering (DLS) and electrophoretic light scattering (ELS) techniques to provide accurate and reliable data on particle characteristics.

The nanoparticle size
was measured using a Nanopartica Nanoparticle
Analyzer SZ-100 (Horiba Scientific). For size measurement, 5 μL
of each sample (AuNP, AuNP-HASH, AuNP-HASHDox, PNC, and AuNP-PEG)
were diluted up to 2 mL with water (pH 6.5) in 3 mL cuvettes. Size
measurements were performed thrice with each trial done in triplicates,
which then were averaged. For zeta potential measurements, the samples
were diluted in water and dispersed in the zeta potential capsules.
The samples were measured by using a Nanopartica Nanoparticle Analyzer
SZ-100 (Horiba Scientific).

XRD was done using Bruker AXS D8 advance powder diffractometer equipped with Cu-Kα generator (λ= 1.5405600 Ao). The generator tension was 35 kV. IR was done on Thermo Nicolet Avatar 370 in the spectral range of 4000-400 cm-1. The contact angle of membranes was analyzed by Contact Angle Meter bearing Model No Kyowa DM501. Zeta potential was measured using Horiba Scientific Nano Partica Nano Particle Analyzer SZ-100. SEM of the cross-section of membranes was taken using High-Resolution Hitachi S-4800 Scanning Electron Microscope. BET surface area of samples was characterized by Nova 1000 Quantachrome Instrument by N2 sorption at 77.35K. The concentration of the permeate samples from filtration experiment was measured using Thermoscientific UV-Vis Spectrophotometer in the visible range of 200-800 nm. The membrane filtration unit consisted of a cylindrical chamber with a membrane adapter connected to a pressure gauge of 2 psi and a peristaltic pump Model No RH-P120 VS Contact angle measurement was done by Sessile drop method by KYOWA InterFace Measurement and Analysis System FAMAS.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
