How it works

Morphological workflow with MDRS The Morphologi 4-ID measurement procedure can be split into five sections: 

Sample preparation  
Spatial separation of individual particles and agglomerates is critical to robust results.  The integrated dry powder disperser makes preparing dry powder samples easy and reproducible. The applied dispersion energy can be precisely controlled, enabling the measurement process to be optimized for a range of material types.  Accessories that fit directly in to the Morphologi 4-ID’s automated stage are available for preparing suspended or filtered samples. 

Image capture 
The instrument captures images of individual particles by scanning the sample underneath the microscope optics. The Morphologi 4-ID can illuminate the sample from below or above, whilst accurately controlling the light levels. 

Image processing 
Use of either the automated ‘Sharp Edge’ segmentation analysis or the manually-controlled thresholding enables the detection of particles and the calculation of a range of morphological parameters for each.

MDRS 
Components and particles of interest are targeted for Raman analysis.  Particles can be selectively targeted based on their morphology, or particles representative of the whole sample can be targeted objectively by the Morphologi software.

Result generation 
Advanced graphing and data classification options in the software ensure that extracting the relevant data from the measurement is straightforward, via an intuitive visual interface.  Correlation scores to a reference library are calculated for each Raman spectrum acquired, enabling particles to be classified based on their chemistry.  The morphological data associated with the particles in each chemical class is used to generate size and shape distributions, delivering component-specific morphological information.  Individually-stored grayscale images for each particle are linked to their Raman spectra and provide qualitative verification of the quantitative results.

Accessories

Appropriate dispersion of the individual particles and agglomerates within a sample leads to robust and reliable results. Good spatial separation and representative sampling of the particles is required. To achieve this, a number of dispersion options are available with the Morphologi 4-ID.

Easy, reproducible, automated sample dispersion
Morphologi 4-ID comes with an integrated dry powder dispersion unit. It enables simple, reproducible preparation of dry powder samples. A precise amount of sample is dispersed automatically using a unique compressed air dispersion mechanism controlled from within the software, for reproducible dispersions every time. 

Optional accessories – for analysis of particles in suspension
A range of instrument accessories supports preparation of samples on microscope slides, in wet suspensions or on filters, extending the capability of the Morphologi 4-ID beyond the characterization of dry sample dispersions. Each accessory fits directly into the automated stage area and is easily selectable in the Morphologi software.

Identification software

Accessories to use when analyzing particles in suspension

2-slide and 4-slide holders

‘Sandwiching’ a few μL of a suspension of smaller particles between a microscope slide and a cover slip is a traditional method of sample preparation for microscopy. Samples are presented in this form to the Morphologi G3-ID using either the 2-slide or 4-slide holder. Slides suitable for chemical identification applications are available.

Thin-path wet cell

The thin-path wet cell is designed for both morphological and chemical characterization of up to 100 μL of sample. It is ideal for applications such as the identification of subvisible particles in therapeutics (described by guidance in USP <787> and USP <788>), especially when a traditional membrane filtering approach may risk changing particles of interest, such as protein aggregates.

Accessories to use when analyzing particles captured on a membrane filter

25 mm and 47 mm diameter filter holders

Methods which are used to detect and characterize particles in suspension often rely on filtering the sample in order to capture particles on a membrane filter. Dedicated filter holders (25 mm or 47 mm diameter) and also the 2-slide holder (see above) allow samples on filter membranes to be presented directly to the Morphologi G3-ID for analysis.

Fused silica filters and holder

Fused silica filters are designed to enable the analysis of filtered samples containing low-contrast particles, such as protein aggregates or contaminant particles.  The fused silica filters are housed in a support for ease of handling, and are presented to the Morphologi in the fused silica holder, which can hold up to 2 filters.

Key applications

Morphologi 4-ID provides value in a wide range of applications, some of which are described below:

Building materials 
Cement is a complex mixture of minerals and additives, the component-specific particle properties of which affect final product performance.  The capability of the Morphologi 4-ID system to analyze and characterize specific particle populations within a cement blend enables different batches or products to be compared, aiding product development and solving production problems.  It brings new insight to conventional cement manufacture and supports industry objectives to incorporate environmentally sustainable replacement materials, such as fly ash and blast furnace slag.

Energy storage/batteries  
Morphologi ID systems can support product development and ensure final product quality by providing information on the chemical composition and structure of electrode materials, enabling their correlation with battery performance.

Forensics
Forensic analysis requires physical and chemical information to interpret evidence.  Raman spectroscopy is routinely used in forensic investigations and combining this with automated imaging provides enhanced insight into the physical and chemical properties of unknown and complex mixtures, allowing differentiation between morphologically similar substances.  The particle size, shape and chemical information delivered by Morphologi systems enables the detection of counterfeit pharmaceuticals or illicit drugs, the identification of contaminant particles in powders, and the examination of soils and other residues from crime scenes to support the investigative process. 

Mining and minerals 
The morphology of geological deposits helps trace the extent of natural disasters and predict the impact of future environmental events. Particle properties also determine the effectiveness of abrasive minerals for use in cutting and polishing tools. Morphologi automatically generates the statistically relevant, component-specific particle data required to meet these challenges.

Pharmaceutical development 
Morphologi ID systems are used by companies across various stages of the pharmaceutical development cycle. The rapid, chemical component-specific morphological information helps to optimize and control both API and excipient particle size and shape during development, and throughout formulation and processing.  For generics, this information can be used to simplify and solve deformulation challenges and help establish in vitro bioequivalence. It can also be used to detect anomalies, contaminants and pinpoint process deviations during manufacturing.
