The system works by nebulizing the liquid suspension into an aerosol and then using scanning mobility particle sizing to analyze the particles. The LNS provides direct measurement of particle number concentrations and can detect small changes in particle size distributions. It has demonstrated accurate sizing for particles from 5-500 nm and measurement of filter retention for particles as small as 10 nm. The system allows detailed analysis of polishing slurries and effects of handling on particle size distributions.
This document discusses techniques for characterizing nanobubbles, including dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), and resonant mass measurement (RMM). DLS and NTA can measure nanobubble size distributions but DLS results may be influenced by contaminants. RMM can distinguish nanobubbles from contaminating particles by measuring buoyant mass. The document also examines measuring nanobubble zeta potential to characterize surface charge and stability. A variety of techniques provide complementary characterization of nanobubbles but RMM can uniquely discriminate bubbles from other particle types of similar size.
Turbidity poster presentation final editKala Drake
Turbidity is caused by particles suspended in water that scatter light, making the water appear cloudy. For a school project, students developed methods to measure turbidity without expensive laboratory equipment. They created a series of standard solutions by mixing specific ratios of barium chloride and sulfuric acid, known as McFarland standards, which produce consistent levels of turbidity. The students then calibrated a simple turbidity tube and a spectrophotometer using the McFarland standards and measured turbidity in pond water samples. Both methods produced similar results, with the tube suitable for field use but less precise and the spectrophotometer more accurate but requiring a lab setting.

POLYMERS: MOLECULAR WEIGHT DETERMINATION GEL PERMEATION CHROMATOGRAPY /SECsana shaikh
Gel permeation chromatography (GPC) is used to determine the molecular weight distribution of polymers. GPC separates polymer molecules of different sizes as they pass through columns containing porous gel beads. Smaller molecules penetrate deeper into the pores than larger molecules, allowing separation by "effective size in solution." Detectors then provide data used to calculate number average molecular weight, weight average molecular weight, and molecular weight distribution. GPC is a convenient and common technique for characterizing polymer molecular weights.

Scale-up of high area filters for microfiltration of biological fluids - Poin...MilliporeSigma
Scale-up of high area filters for biological fluid microfiltration requires accounting for multiple factors to ensure reliable scaling. Key factors include variability in membrane and device properties, process conditions, and non-membrane pressure losses. High area filters have increased productivity but scaling is more complex. Proper device design and narrowing the performance range of small-scale devices improves scaling accuracy. Accounting for pleat density, height, and support permeability is important. High area filters scale linearly for plugging streams but non-linearly for streams where surface caking occurs. A scaling tool with identical pleat structure confirms expected performance.

Many Advantages of the LNS System
Highly sensitive since individual particles are
counted.
Actual particle concentrations, not relative
concentrations, are measured directly.
Shape of the particle size distribution is
not assumed.
Technique is independent of optical
properties of the particles.
Suitable for on-line or off-line measurements.

Real Slurries often have several modes
Particle populations are generally log-normal
• Particle Populations
often follow Log-
Normal Distribution
• Log normal
distribution defined
by three variables
– Peak Diameter
– Geometric
Standard Deviation
– Total integrated
concentration
• Multimodal and
skewed distributions
not accurately
represented by
single mode
statistics

• Automatically
generated in Kanolysis
– Sum of single
distributions fit to raw
data
– Individual modes may
be defined by
separate log-normal
distributions
• Peak Diameter

Engineering Use: Slurry Turnover Limit
Size profile vs number of slurry turnovers shows onset of agglomeration
• After too many slurry turnovers, the number of large diameter particles
increased to an unacceptable “Bad” limit. Peak Diameter also shifted larger.
Likely due to agglomeration effects.
• The LNS system was able to resolve this subtle difference
– Detect small shifts in individual modes
– Detect changes in ratios of mode concentrations
– Detect changes in mode shape (e.g. increased dimers)

Aerosolization
Sample Concentration Effects
• Each nebulized droplet
contains the same
concentration of Dissolved
Non-Volatile Residue
• Size of Precipitated Non-
Volatile Residue particle
proportional to the parent
droplet size
• High concentration of
Dissolved Non-Volatile
Residue may overlap native
particle size distribution
• Artifact dimers form when
two separate particles are
coincident in a single droplet

Liquid Nanoparticle Sizer (LNS)
Concentration Effects- Identifying artificial dimers
• Artificial dimers are
caused by the
presence of two
discrete colloid
particles within a single
droplet
• The probability of a
single droplet
containing multiple
particles is proportional
to droplet diameter and
colloid concentration:
P2+ C x Ddroplet

• Eliminating large
droplets allows for
higher concentrations
of discrete aerosolized
colloid particles

Liquid Nanoparticle Sizer (LNS)
Principle of Operation – Ion Mobility Spectrometer
• Annular Flow Ion
Mobility Classifier
(AFIMC) acts as a
“bandpass” filter
based on particle
size
• Measurement of
particle
concentrations over
a range of selected
sizes provides
particle size
distribution
information
• Data inverted to
account for
charging and
detection efficiency

Liquid Nanoparticle Sizer (LNS)
Principle of Operation - Condensation Particle Counter
• Used as particle detector
at the exit of the AFIMC
• Heated Saturator adds
butyl alcohol vapor to the
aerosol
• Cooled Condenser
causes the butyl alcohol
vapor to become
supersaturated
• Supersaturated butanol
vapor condenses onto
particles in the aerosol
making large droplets
• Droplets counted optically
using light scattering
(“Dry” particles are not
detected)
