    IDEXX Laboratories, Inc. is an American multinational corporation [3] [4] engaged in the development, manufacture, and distribution of products and services for the companion animal veterinary, livestock and poultry, water testing, and dairy markets.

  3. Sample preparation - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation

    In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species .

  4. Sample preparation in mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation_in_mass...

    Sample preparation for mass spectrometry is used for the optimization of a sample for analysis in a mass spectrometer (MS). Each ionization method has certain factors that must be considered for that method to be successful, such as volume, concentration , sample phase, and composition of the analyte solution.

  5. Laboratory diagnosis of viral infections - Wikipedia

    en.wikipedia.org/wiki/Laboratory_diagnosis_of...

    A wide variety of samples can be used for virological testing. The type of sample sent to the laboratory often depends on the type of viral infection being diagnosed and the test required. Proper sampling technique is essential to avoid potential pre-analytical errors.

  6. Toxicity characteristic leaching procedure - Wikipedia

    Sample preparation for leaching; Sample leaching; Preparation of leachate for analysis; Leachate analysis; In the TCLP procedure the pH of the sample material is first established, and then leached with an acetic acid / sodium hydroxide solution at a 1:20 mix of sample to solvent. For example, a TCLP jug may contain 100g of sample and 2000 mL ...

  7. Liquid-based cytology - Wikipedia

    en.wikipedia.org/wiki/Liquid-based_cytology

    Brushes used to collect samples for cytology. Liquid-based cytology is a method of preparing samples for examination in cytopathology.The sample is collected, normally by a small brush, in the same way as for a conventional smear test, but rather than the smear being transferred directly to a microscope slide, the sample is deposited into a small bottle of preservative liquid.

  8. Western blot - Wikipedia

    en.wikipedia.org/wiki/Western_blot

    Western blot workflow. The western blot (sometimes called the protein immunoblot), or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. [1]

  9. Calibration curve - Wikipedia

    en.wikipedia.org/wiki/Calibration_curve

    A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.
