SALD-7500nano

The SALD-7500nano Nano Particle Size Analyzer by Shimadzu represents a significant advancement in nanoparticle analysis, offering unparalleled sensitivity and a broad measurement range to cater to diverse research and industrial applications.

Exceptional Sensitivity and Real-Time Analysis

Delivering ten times the sensitivity of previous models, the SALD-7500nano enables continuous monitoring of particle size and distribution changes at one-second intervals. This real-time analysis is crucial for applications requiring immediate feedback on particle behavior.

Comprehensive Measurement Range

The analyzer covers an extensive particle size range from 7 nm to 800 μm, allowing for the assessment of primary nanoparticles, sub-visible particles, and contaminants using a single light source and optical system. This wide range facilitates the evaluation of dispersion and aggregation characteristics under various conditions.

Innovative Optical Design

Incorporating Shimadzu’s proprietary Scattered Light Intensity Trace (SLIT) optical system, the SALD-7500nano captures forward-scattered light up to a 60° angle on a single detector face. This design ensures high-resolution measurements in the fine particle region without data discontinuities, enhancing accuracy across the entire measurement spectrum.

Advanced Detection with Wing Sensor II

Equipped with the high-resolution, high-sensitivity Wing Sensor II, featuring 76 elements for forward-scattered light detection and additional elements for side and back-scattered light, the analyzer accurately captures light intensity distribution patterns. This capability enables precise measurement of particle size distributions over a wide diameter range.

Stable and Maintenance-Friendly Optical System

The Omnidirectional Shock Absorption Frame (OSAF) isolates all optical components from shocks and vibrations, maintaining system stability and eliminating the need for frequent optical axis adjustments. Built-in self-diagnostic functions facilitate easy maintenance by monitoring sensor outputs and operational status, ensuring consistent performance.

Compliance and Validation

The SALD-7500nano complies with ISO 13320 and JIS Z 8825-1 laser diffraction and scattering standards, ensuring reliable and standardized measurements. Performance validation is possible using JIS standard particles, allowing users to verify instrument accuracy and measurement validity.

Automatic Refractive Index Calculation

Addressing the challenges of selecting appropriate refractive indices, the analyzer features an automatic refractive index calculation function based on the Light Intensity Distribution Reproduction (LDR) method. This innovation simplifies the measurement process by eliminating trial-and-error in refractive index selection.

Flexible System Configuration

The SALD-7500nano offers versatile system configurations to accommodate various sample types and measurement conditions:

• Small-Volume Measurement System: Combining the SALD-7500nano with the SALD-BC75 batch cell enables measurements with minimal sample and dispersion medium volumes, reducing waste and facilitating the analysis of limited or expensive samples.
• High-Concentration Sample Measurement System: Integrating the SALD-7500nano with the SALD-HC75 allows for accurate measurement of high-concentration samples without dilution, preserving the original state of the sample and providing true representation of particle size distribution.
• Ultra Small-Volume Measurement System: By adding “Glass Slides with Indentation” to the high-concentration sample measurement system, the analyzer can measure ultra-small sample volumes, enhancing its applicability to precious or limited-quantity samples.

User-Friendly Operation

The SALD-7500nano is designed for ease of use, featuring:

• PC-Controlled Sampler (SALD-MS75): Facilitates the dispersion and circulation of particle groups in a liquid medium, with components like a stirrer, ultrasonic sonicator, and pump ensuring thorough mixing and consistent sample delivery to the flow cell.
• Solvent Compatibility: Supports the use of most organic solvents as dispersion media, broadening the range of samples that can be analyzed.
• Efficient Maintenance: The cell and cell holder can be easily accessed and replaced using a slide mechanism, simplifying routine maintenance tasks.

Applications Across Diverse Fields

With its advanced measurement capabilities, the SALD-7500nano is suitable for a wide array of applications, including:

• Nanotechnology: Characterizing nanoparticles and nanomaterials.
• Life Sciences: Analyzing biological samples, such as proteins and viruses.
• Fine Bubbles: Investigating microscopic bubbles in liquids.
• Material Science: Evaluating the properties of new materials, including cellulose nanofibers and gold nanoparticles.
