Determination of Liquid Density

Author(s)
Lane C. Sander, Lorna T. Sniegoski
The determination of solution density is required for conversion of liquid solution levels from a mass fraction basis to a volume fraction basis. This

Plumbing for Liquid Chromatography

Author(s)
Lane C. Sander
The setup and maintenance of liquid chromatographic equipment requires a basic knowledge of chromatographic hardware. Tubing connections are an essential

Preparation of Calibration Solutions

Author(s)
Lane C. Sander, Michele M. Schantz
Calibration solutions provide the basis for quantitation for most instrumental techniques. The instrumental responses for analytes in calibrants of known

Pressurized Fluid Extraction

Author(s)
Lane C. Sander
Pressurized fluid extraction (PFE) is one of several sample preparation methods that can be used to extract targeted analytes from a sample matrix into a

Principles of Quantitation: Chromatography

Author(s)
Lane C. Sander
The accurate characterization of the chemical composition of a sample depends on a variety of factors that must be considered by the analyst. Knowledge of how

Sample Concentration and Processing

Author(s)
Lane C. Sander
Sample Concentration and Processing Sample concentration is a common step in sample preparation prior to analysis that is performed to increase method

Sorting carbon nanotubes

Author(s)

Sorting of single-wall carbon nanotubes by their electronic and atomic structures in liquid phases is reviewed in this chapter. We first introduce the sorting

Soxhlet Extractions

Author(s)
Lane C. Sander
Soxhlet extraction is one of several sample preparation methods that can be used to transfer targeted analytes from a sample matrix into a solvent, to permit

Use of Analytical Balances

Author(s)
Lane C. Sander
The determination of mass is a fundamental component in quantitative analysis, and weighing accuracy is an important factor for most applications. This

Volumetric Transfer of Liquids

Author(s)
Lane C. Sander
Although volumetric measurements are usually less accurate than gravimetric based measurements, volumetric measurements are still in common use due to the

What is Chromatography All About?

Author(s)
Lane C. Sander
Chromatography is an example of a process by which a mixture is separated into at least two fractions with different compositions. Other separation methods

Gapped Excitation in Dense Kondo Lattice CePtZn

Author(s)
Leland Weldon Harriger, Steven M.T. Disseler, J. Gunasekera, Jose A. Rodriguez, J. Pixley, P. Manfrinetti, S. K. Dhar, D. K. Singh
We report on neutron υSR scattering studies of dense Kondo lattice CePtZn. The system develops long range incommensurate magnetic order as the temperature is
