Q1. What is the ESI and APCI difference? What is the way of development of method for Impurities??
Ans. 
ESI and APCI are ionization techniques used in mass spectrometry. Method development for impurities involves identification, quantification, and validation.
• ESI (Electrospray Ionization) and APCI (Atmospheric Pressure Chemical Ionization) are ionization techniques used in mass spectrometry.

• ESI is suitable for polar and ionic compounds, while APCI is suitable for nonpolar and less polar compounds.

• ESI involves the formati...read more

Q2. Quadrapoles functioning
Ans. 
Quadrapoles are used in mass spectrometry to filter ions based on their mass-to-charge ratio.
• Quadrapoles use radio frequency and direct current voltages to selectively filter ions.

• They are composed of four parallel rods that create a quadrupole electric field.

• Ions with a specific mass-to-charge ratio will oscillate within the field and pass through the filter.

• Quadrapoles are commonly used in tandem mass spectrometry fo
