  • Chemical Safety

    People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

  • What are Compound Microscopes?

    Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

    In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.

  • Harmful Chemicals Found In Food

    It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...

  • What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support

    Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...

Solubility Product Constant

Equilibrium constant that applies to the dissolution of a slightly soluble compound.

Radiation

High energy particles or rays emitted during the nuclear decay processes.

Chain Termination Step

The combination of two radicals, which removes the reactive species that propagate the change reaction.

Nuclides

Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.

Integrated Rate Equation

An equation giving the concentration of a reactant remaining after a specified time, has different mathematical form for different orders of reactants.

Coulomb

Unit of electrical charge.

Composition Stoichiometry

Descibes the quantitative (mass) relationships among elements in compounds.

Eluant or eluent

The solvent used in the process of elution, as in liquid chromatography.

 

Enzyme

A protein that acts as a catalyst in biological systems.

Lewis Acid

Any species that can accept a share in an electron pair.

Salicylaldehyde

An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.

Ion Product for Water

Equilibrium constant for the ionization of water, Kw = [H3O+][OH-] =1.00 x 10-14 at 25 °C.

Law of Partial Pressures (Dalton's Law)

The total pressure exerted by a mixture of gases is the sum of the partial pressures of the individual gases.

Periodicity

Regular periodic variations of properties of elements with atomic number (and position in the periodic table).

Heterogeneous Mixture

A mixture that does not have uniform composition and properties throughout.

Cohesive Forces

All the forces of attraction among particles of a liquid.

Reverse Osmosis

Forcing solvent molecules to flow through a semipermable membrane from a concentated solution into a dilute solution by the application of greater hydrostatic pressure on concentrated side than the osmotic pressure opposing it.

Eluate

Solvent (or mobile phase) which passes through a chromatographic column and removes the sample components from the stationary phase.

Peroxide

A compound containing oxygen in the -1 oxidation state. Metal peroxides contain the peroxide ion, O22

Dilution

Process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent.
