Boiler water & steam quality, cooling system & water consumption, coal analysis as per IS standard.

• Boiler water quality refers to the purity of water used in boilers to prevent corrosion and scale buildup.

• Steam quality is the measure of the amount of moisture in steam, with higher quality steam having less moisture.

• Cooling system quality control involves monitoring water quality to prevent fouling and corrosion in the system.

• Water consumption in cooling systems should be opti...read more

CCP stands for Critical Control Point in milk processing.

• CCP is a step in the process where control can be applied to prevent, eliminate or reduce a hazard to an acceptable level.

• It is a point in the process where failure to control can result in an unacceptable safety risk.

• Examples of CCPs in milk processing include pasteurization, homogenization, and packaging.

• CCPs are identified and monitored as part of a Hazard Analysis and Critical Control Points (HACCP) plan.

• The goal of...read more

Yes, I am familiar with the analysis of iron ore.

• Iron ore analysis involves determining the chemical composition and physical properties of the ore.

• Common methods used for analysis include X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS), and inductively coupled plasma mass spectrometry (ICP-MS).

• Chemical analysis helps determine the percentage of iron and impurities present in the ore.

• Physical analysis includes measuring particle size distribution, moisture cont...read more

Strong acids are highly corrosive substances that completely dissociate in water to release hydrogen ions.

• Strong acids have a pH value less than 1.

• They are highly reactive and can cause severe burns and damage to living tissues.

• Examples of strong acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3).

Instrument handling involves operating, maintaining, and troubleshooting various laboratory instruments used for quality control testing.

• Operate instruments according to standard operating procedures

• Calibrate instruments regularly to ensure accuracy

• Troubleshoot instrument issues and perform basic maintenance

• Keep detailed records of instrument usage and maintenance

• Train other staff members on proper instrument handling techniques

Chemical analysis involves various techniques to identify and quantify the components of a substance.

• Quantitative analysis - determining the amount of a particular substance in a sample

• Qualitative analysis - identifying the components present in a sample

• Instrumental analysis - using instruments like spectrophotometers, chromatographs, and mass spectrometers

• Wet chemical analysis - traditional methods involving chemical reactions in solution
