Shimadzu SALD-2300 Laser Diffraction Particle Size Analyser

Shimadzu SALD-2300 Laser Diffraction Particle Size Analyzer  (CCRL22)

Located in room 2018 of the Science Center Building of the Armstrong Campus.

The Shimadzu SALD-2300 is a highly versatile laser diffraction particle size analyzer capable of measuring a vast array of materials, from 17 nm to 2,500 μm, in both wet and dry states. It is primarily used to ensure product quality in industries such as pharmaceuticals, cosmetics, food and beverage, electronics, and ceramics.

Supported Sample Types

The SALD-2300 handles a broad spectrum of materials across various physical states and concentrations:

• • • • Wet Materials: Analyzes suspensions and emulsions, including milk fat, personal care products, and lithium-ion battery materials. It can even measure complex samples like red wine in its undiluted state.

      • Dry Powders: Using the SALD-DS5 "Cyclone" injection device, it measures dry materials like metal powders and their oxides, effectively breaking up agglomerates for accurate results.

      • High-Concentration Samples: Capable of measuring samples with concentrations up to 20% without dilution, which is critical for hand creams, face creams, and ointments that might agglomerate or disperse if diluted.

      • Extreme Particle Sizes: Can measure both tiny particles like 50 nm polystyrene latex (PSL) and large items like 2 mm stainless steel balls with the same instrument.

Core Capabilities

• • • • Wide Measurement Range: Covers particle sizes from 17 nm to 2,500 μm.

      • Broad Concentration Range: Detects particles in concentrations ranging from 0.1 ppm to 20%, allowing for the evaluation of dissolution processes where concentration changes over time.

      • Real-Time Measurement: Provides continuous data at minimum one-second intervals, allowing users to monitor shifts in dispersion or aggregation in real-time.

      • High Resolution: Features the Wing Sensor II with 78 concentric detector elements that, along with side and backscatter sensors, can accurately identify multiple peaks in complex particle size distributions.

      • Advanced Software Functions:

        • Automatic Refractive Index: The WingSALD II software can automatically calculate the appropriate refractive index using the LDR (Light Intensity Distribution Reproduction) method.

        • Data Emulation: Can simulate results to match older instruments, aiding in data continuity during equipment upgrades.

      • Adaptable Configurations: Offers multiple sampling units, including a batch cell for small quantities (12 mL), a variable-volume sampler (100–300 mL), and a high-concentration system requiring as little as 15 μL of sample.
