Many other goals lie ahead for the further advancement of the membrane chlor-alkali process and technology. Asahi is dedicated to achieving these goals and to providing new standards of efficiency and performance in the future. 

Ultracentrifugation is a common and powerful method in the separation of biological materials. Despite its widespread use, however, few investigators fully exploit its capabilities. As a result, run times are unnecessarily long and separations are indistinct. In the long run, the efficiency and performance of the laboratory suffer. 

Shen et al. have reported studies on procaine-selective electrodes embodying PVC membranes [57]. Various ion-pair complexes (procaine derivatives with tetraphenylborate, dipicrylamine, tetraiodomecurate, and reineckate) were incorporated into platinized PVC membranes, and with dinonyl phthalate as the solvent mediator, formed procaine selective electrodes. The efficiency and performance of these were compared, and it was found that procaine picrylamine and procaine tetraphenylborate were the best electroactive materials. The procaine picrylamine electrode exhibited a Nemstian response over the range 10 pM to 0.1 M, and was used as the indicator electrode for the potentiometric determination of procaine. The method recovery was found to be 99.8%, with a standard deviation of 0.9%.

The removal of fine particles from gases and liquids is a subject of permanent industrial interest. By contrast, only solid-liquid systems are analytically or clinically relevant in this respect. Ultrasound power may help improve the efficiency and performance of analytical separation methods. The specific mechanisms by which separation processes can be ultrasonically enhanced vary with the nature of the medium to be treated. 

Because the function of a fuel is to produce heat, the calorific or heating value (ASTM D-240, IP 12) is one of the important fuel properties and a knowledge of this value is necessary in obtaining information regarding the combustion efficiency and performance of all types of oil-burning equipment. 

Lean-bum engine technologies such as gasoline direct injection and diesel engines can provide significant improvements in fuel efficiency and performance. 

In contrast to the OQ procedures where all parts of the plant and equipment are qualified separately, the PQ procedures qualify the entire plant with respect to the production process. The definition given for PQ is valid for retrospective validation as well as for prospective validation. While carrying out PQ processes, all necessary SOPs (e.g., for the use or cleaning of the plant) should be approved. Values of critical and noncritical process parameters recorded during PQ must be collected to evaluate the efficiency and performance of the plant. 

In collaboration with the CaFCP, once the fuel cell buses are delivered and the hydrogen fueling and vehicle maintenance facilities are completed, NREL will begin collecting and evaluating data that will help to demonstrate that fuel cell buses can be fueled and maintained efficiently and perform consistently. 

Allows evaluation of various strategies for changing either the raw material, fuels sources, or plant modification to improve efficiency and performance. 

The general principles of chromatography have been discussed in Chapter 2. However, a more detailed account in the context of GC is presented herein the reader is also referred to the Glossary for additional detail and explanations of the terminology used. The treatment of theoretical aspects is at a level which should enable the analyst to obtain maximum efficiency and performance from the system and application.
