  2. Matrix isolation - Wikipedia

    en.wikipedia.org/wiki/Matrix_isolation

    Using the matrix isolation technique, short-lived, highly-reactive species such as radical ions and reaction intermediates may be observed and identified by spectroscopic means. For example, the solid noble gas krypton can be used to form an inert matrix within which a reactive F 3 − ion can sit in chemical isolation. [1]

  3. Matrix (chemical analysis) - Wikipedia

    en.wikipedia.org/wiki/Matrix_(chemical_analysis)

    A(standard) is the peak area of analyte in the absence of matrix. The concentration of analyte in both standards should be the same. A matrix effect value close to 100 indicates absence of matrix influence. A matrix effect value of less than 100 indicates suppression, while a value larger than 100 is a sign of matrix enhancement.

    MALDI is an ionization technique where laser energy is absorbed by a matrix to create ions from large molecules without fragmentation. The matrix, typically in excess, is mixed with the analyte molecule and deposited on a target. A table of matrix compounds, their structures, laser wavelengths typically used, and typical application is shown below.

  6. Matrix analysis - Wikipedia

    en.wikipedia.org/wiki/Matrix_analysis

    In mathematics, particularly in linear algebra and applications, matrix analysis is the study of matrices and their algebraic properties. [1] Some particular topics out of many include; operations defined on matrices (such as matrix addition, matrix multiplication and operations derived from these), functions of matrices (such as matrix exponentiation and matrix logarithm, and even sines and ...

  7. List of named matrices - Wikipedia

    en.wikipedia.org/wiki/List_of_named_matrices

    An "almost" triangular matrix, for example, an upper Hessenberg matrix has zero entries below the first subdiagonal. Hollow matrix: A square matrix whose main diagonal comprises only zero elements. Integer matrix: A matrix whose entries are all integers. Logical matrix: A matrix with all entries either 0 or 1.

  8. Standard addition - Wikipedia

    en.wikipedia.org/wiki/Standard_addition

    This method is useful for analyzing complex samples where a matrix effect interferes with the analyte signal. In comparison to the calibration curve method, the standard addition method has the advantage of the matrices of the unknown and standards being nearly identical. [1]

    The above video is certainly not conclusive evidence of widespread ilcliteracy — but you don’t have to look especially hard to find it. Whether listening to a popular song, watching a television show, seeing a film or reading a magazine, the totality of human sexual pleasure is often reduced to a penis penetrating a vagina.
