NTA Particle Tracker

Purpose

The NTA Particle Tracker skill provides single-particle tracking analysis for nanoparticle size and concentration measurements, offering particle-by-particle characterization through direct visualization.

Capabilities

Single-particle tracking
Size-concentration profiles
Fluorescence NTA mode
Real-time size distribution
Particle count and concentration
Sample heterogeneity assessment

Usage Guidelines

NTA Measurement

Sample Preparation
- Dilute to 10^7-10^9 particles/mL
- Avoid air bubbles
- Use appropriate buffer
Acquisition
- Optimize camera level
- Set detection threshold
- Record multiple videos
Analysis
- Track minimum 1000 particles
- Set minimum track length
- Generate size-concentration plot

Process Integration
