As such, gas mixtures are produced based on the molecular weight of each gas component in the mixture. The gravimetric process is the most accurate method for producing calibration gases and is not affected by temperature or pressure.Other methods (e.g., dynamic blending, pressure blend...
Crystallization and Structure Determination—Crystals of four VAO mutants were grown at 20 °C by the hanging-drop vapor diffusion method. The drops contained 4 μl of an equal mixture of protein solution (6.5-13 mg/ml) in 50 mm potassium phosphate (pH 7.5) and reservoir solution containing ...
A vapor reaction method including the steps of providing a pair of first and second electrodes within a reaction chamber where the pair of electrodes are arranged substantially para
Needle stick injuries are particularly likely to occur in resheathing the needle and this practice should either be discouraged or a safer method of resheathing be used, perhaps with the aid of certain newly developed devices. Vacuum collection tubes minimize several of the hazards and problems of...
