70. pH pH is a unit of measurement which describes the degree of acidity or alkalinity of a solution. pH refers to a combination of p for power and H for the symbol of the element hydrogen. pH is defined in chemistry as the negative log of the activity of the hydrogen ion: pH=-log10H+ pH is a measurement of the activity of hydrogen ions in a solution at a given temperature. Activity is a function of the availability of hydrogen ions and not their concentration in a solution. pH is measured on a scale of 0 to 14 where pH values less than 7 are considered acidic and values greater than 7 are alkaline.

72. pH Meter Oakton pHTestr 2 Compact, portable pH meter. Features of this meter include one-piece body design, microprocessor control with digital display, and automatic temperature control (ATC).
73. pH Meter Calibration (1) Calibration PH meters must be calibrated properly and regularly to provide accurate readings. The OAKTON pHTestr 2 uses up to three-point calibration (pH 4, 7,and 10) and automatically recognizes the selected buffer. 1. Turn the instrument on using the ON/OFF button. 2. Dip the electrode end of the unit into the selected buffer (pH 4, 7, or 10) up to the color band. Immersing the unit deeper into the test solution could damage electronic components in the instrument.
74. pH Meter Calibration (2) Calibration (cont’d) 3. Press the CAL button. The instrument is in calibration mode and “CA” will appear on the display. Calibration begins when a number close to the selected buffer starts to flash on the display. 4. After about 30 seconds confirm calibration by pressing the HOLD/CON button. If calibration is confirmed, “CO” will appear on the display. The buffer value reading will then be shown on the display. 5. The procedures listed in steps 2-4 are then repeated using the other two buffers, if desired. 6. Periodically check the calibration of the instrument to verify proper operation. Full calibration of the instrument should be performed daily. Confirmation of calibration with a known buffer solution should be performed before, and after the measurement of a set of samples.

Develop and enforce regulations: EPA works to develop and enforce regulations that implement environmental laws enacted by Congress. EPA is responsible for researching and setting national standards for a variety of environmental programs, and delegates to states and tribes the responsibility for issuing permits and for monitoring and enforcing compliance. Where national standards are not met, EPA can issue sanctions and take other steps to assist the states and tribes in reaching the desired levels of environmental quality. Product Quality—Standards and Verification USP establishes public standards to help assure good quality medicines, dietary supplements, and related products used to maintain health and treat disease. Prescription and over-the-counter medicines available in the United States must, by federal law, meet USP's public standards, where such standards exist. Many other countries require the use of high-quality standards such as USP's to assure the quality of medicines and related products. USP disseminates its standards to pharmaceutical manufacturers, pharmacists, and other users through its USP–NF and other publications, official USP Reference Standards materials, and Pharmacopeial Education courses.
Members of the AOAC Laboratory Accreditation Criteria Committee (ALACC) have provided laboratory managers with the guidance they need to meet ISO 17025 requirements. AOAC also provides a number of key publications, hosts technical meetings and conferences, and offers training courses in the areas of laboratory management, quality assurance, accreditation, statistics, and measurement uncertainty.
Developing validated standards methods of analysis for pharmaceutical and health related products Publishing validated standard methods in the compendium the USP. Distributing references materials to be used with the methods outlined in the Pharmacopoeia USP operates two programs to promote safer care of patients who take medications and stay in hospitals. The Medication Errors Reporting Program allows healthcare professionals to directly report medication errors to USP. MEDMARX® , an Internet-based medication error and adverse drug reaction reporting program, is designed for use in hospitals and health systems. USP also uses its knowledge base to provide information that supports the healthcare community in the research and development of patient safety initiatives.
Certain transducers , such as strain gages and pressure transducers , have fatigue life that can change accuracy , depending on the duration and cyclic behavior of the mesurand. In some cases accuracy is not as the importance to detect small change (resolution) , as when quantities are being compared. Such an example is under ground tank testing , the interface between the liquid and the air can be located by observing a small temperature change between the air and liquid. Natural hazards : wiring and the connectors must be able to withstand the effects of exposure to in the required environment, dust, dirt high or low temperatures, water including salt water, humidity, solvents such as acids , bases. The transducer should not pose a hazard to the environment in which it is placed , including electrical problems such as explosion hazard or shock hazard. Power requirements are dependent on type of transducer. Passive transducers such as photocells , convert some of the incident source energy into electrical energy. An AC or DC source power leads can be come a potential problem if transducer operated in a noisy or remote environment. Signal conditioning : if the transducer produces a very small signal or located in a remote or noisy environment , amplification or other signal conditioning may be required at the transducer. The transducer output may need to be converted into a compatible fromate for the remainder of the instrument system. Physical requirements: the space available may be limited or the measurand may be limited over a limited rage. If the quantity to be measured is concentrated , such as in the case of a collimated light source. The physical sizes of the transducer can affect the output.
When Acids are added to water , they release hydrogen ions into solution. On the other hand when bases are added to water , they cause hydrogen ions to be removed from solution. Strong acids and strong bases completely dissociate when dissolved in water and therefore have a strong effect on the hydrogen ion concentrations. Wek acids and weak bases do not completely dissociate in water and therfore have a smaller effect on theconcentration ofhydrogen ions in the solution.
The human eyes receptors respond to wave of light, which we perceive as color. The human observer perceives only reflected light and sees material as color of the reflected wavelengths. White light (sun light) contain all wavelengths in roughly equal amounts . Before use the instrument is calibrated to 100% transmission (zero absorbance) by inserting a cuvette containing the pure solvent without light-absorbing solute. Cuvettes must be made from materials that is transparent to all wavelengths that might be used. Cuvettes are carefully made so that the light path is 1CM Glass is transparent to visible wavelengths but is opaque to ultra violet.
