Quantum dots - Size determination by SAXS
A dispersion of nanosized CdSe quantum dots was analyzed with the SAXSpace system. The particle size, which is a very crucial parameter for the properties of quantum dots, was determined within a very short time.
Desmearing of Line-smeared Scattering Curves
Small Angle X-Ray Scattering instruments use two different beam geometries - point collimation and line collimation. Using a line shaped beam dramatically reduces the measurement time while maintaining the same data quality.
Protein Mass Determination using Small Angle X-Ray Scattering
The molecular weight of Glucose Isomerase was determined with the SAXSpace small-angle X-ray scattering system. The results are in good agreement with theoretically calculated values from X-ray crystallography data.
Protein Shape Determination by Small Angle X-Ray Scattering
The 3-dimensional shape of Glucose Isomerase in solution was studied with the SAXSpace system. The solution structure of this protein was compared with the crystal structure obtained by X-ray crystallography.
Studying the Internal Structure of Carbon Nanotubes with SAXS
A polymer/multi-walled carbon nanotubes composite was measured with the SAXSpace system. The internal structure of the nanotubes was determined by calculating the electron density profile of the nanotube’s cross-section.
Fast SAXS Measurements of a Diluted Protein Solution
A 1% Lysozyme solution was measured with the SAXSpace system. Structural information can be obtained already after 1 minute due to the highly intense line-collimation mode and the compact design of the SAXSpace system.
Structural Characterization of a Mesoporous Material
A mesoporous material was studied with the SAXSpace system. Important structural parameters like pore size, degree of polydispersity, total volume fraction of the pores and arrangement of the pores were obtained.
Size and Size Distribution of Gold Nanoparticles by SAXS
Gold nanoparticle dispersions were measured with the SAXSpace system. SAXS proved to be a well-suited method for determining the size distribution of a binary mixture of two dispersions with very similar particle size.
An Insight into the Structure of Surfactants
The structure of inhomogeneous (core-shell) nanoparticles was studied with the SAXSpace system. The internal structure of Sodium Dodecyl Sulfate micelles in water was determined by calculating the radial electron density profile.
Studying the Internal Structure of Lamellar Systems
The SAXSpace system was used to characterize nano-structured lamellae present in a surfactant sample. The internal structure (core-shell) of the lamellae could be precisely determined.
Structure Determination of Interacting Sample Systems
Evaluation of interacting (charged or concentrated) particles requires the knowledge of “form and structure factor”. The unique GIFT software allows to study samples in their original state and to determine the nanostructure of the particles.
Coir fibers - SWAXS studies of structural changes induced by tensile stress
Microfibril angle in coir fibers during tensile straining was studied using the SAXSpace system operated in point collimation mode in combination with the integrated TS 600 tensile stage.
Fast Structure Analysis of Pharmaceutical Excipients by SWAXS for Product Quality Control
The nanostructure of pharmaceutical excipients used as taste masking agents was rapidly determined for quick quality control with the SAXSpace system.
Quality control of pharmaceutical excipients during storage and processing
The structure of pharmaceutical excipients as a function of storage time and temperature was analyzed by small- and wide-angle X-ray scattering using the SAXSpace system.
Small Angle X-Ray Scattering with Microcrystalline Materials
SAXS is routinely used for the characterization of liquid crystalline phases. If the crystalline domains are large and the sample is very viscous the scattering is not averaged over all orientations. The RotorCell enables measuring such samples.
Concentration Measurement of Sodium Hydroxide Solutions by Refractive Index
The concentration of sodium hydroxide in water can be easily and quickly determined by refractive index measurement.
Improve Digestion Quality and Save Money – Microwave Digestion rules out Open Digestion
Reliable elemental analysis results need robust sample preparation to destroy sample matrices or to separate matrix from analytes. The sample preparation step is by far the most error-prone and critical step of the analytical procedure.
