Out of Specification (OOS) refers to test results that fall outside predetermined acceptance criteria.

• OOS results indicate that a product does not meet quality standards.

• Common in pharmaceuticals, where potency or purity may be tested.

• Example: A batch of tablets shows a potency of 85% when the specification is 90-110%.

• OOS results trigger an investigation to determine the cause.

• It can lead to product recalls or re-testing if not resolved.

Quality Control (QC) departments commonly use various detectors for accurate analysis of samples.

• UV-Vis Detectors: Used in HPLC for detecting compounds that absorb UV light.

• Fluorescence Detectors: Highly sensitive, used for detecting fluorescent compounds.

• Mass Spectrometry: Provides molecular weight and structure information, often coupled with chromatography.

• Conductivity Detectors: Used for ionic species in solutions, common in ion chromatography.

• Refractive Index Detectors: ...read more

I am proficient in handling various types of office equipment such as printers, scanners, and copiers.

• Printers

This statement suggests an inverse relationship between pH and mV.

• The pH of a solution decreases as the mV increases.

• This relationship is commonly observed in pH measurements using electrodes.

• The inverse relationship can be explained by the fact that as the mV increases, the concentration of H+ ions decreases, leading to a decrease in pH.

• This relationship is important to consider when interpreting pH measurements and ensuring accuracy in experimental results.

Multimill is a versatile machine used for grinding, mixing, and homogenizing various materials.

• Multimill is commonly used in pharmaceutical, food, chemical, and cosmetic industries.

• It can perform multiple functions like granulation, pulverization, and size reduction.

• The machine consists of a high-speed rotor that rotates inside a perforated screen, allowing for efficient processing.

• Multimill is designed to handle both wet and dry materials, making it a versatile tool in manuf...read more

pH slope is the change in pH per unit change in electrode potential.

• It is a measure of the sensitivity of a pH electrode.

• A steeper slope indicates a more sensitive electrode.

• The ideal pH slope is around 59.16 mV/pH at 25°C.

• Factors that can affect pH slope include temperature, electrode age, and solution composition.

pH is a measure of the acidity or alkalinity of a solution on a scale of 0 to 14.

• pH stands for 'potential of Hydrogen'

• It measures the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• Examples: lemon juice has a pH of around 2, pure water has a pH of 7, and baking soda has a pH of around 9
