Sakata Inx R&D Chemist Interview Questions and Answers

HPLC is a technique used to separate, identify, and quantify components in a mixture based on their interactions with a stationary phase and a mobile phase.

• HPLC involves pumping a sample mixture through a column packed with a stationary phase, where different components interact differently and are separated based on their affinity for the stationary phase.

• The separated components are detected as they exit the column a...read more

The formula for an acid is typically written as HX, where X represents an anion.

• Acids are substances that donate protons (H+ ions) in a chemical reaction

• The general formula for an acid is HX, where H represents a hydrogen ion and X represents an anion

• Examples include HCl (hydrochloric acid), H2SO4 (sulfuric acid), and HNO3 (nitric acid)

Motor capacity is in Kw because it measures active power while transformer capacity is in kVA because it measures apparent power.

• Motor capacity is measured in Kw because it represents the active power that the motor can produce.

• Transformers are rated in kVA because they are designed to handle both active and reactive power.

• kVA is a measure of apparent power, which is the combination of active power and reactive power.

• T...read more

Different types of motors include DC, AC, stepper, servo, and linear motors, each with unique applications.

• DC motors are commonly used in household appliances and electric vehicles.

• AC motors are used in industrial machinery and HVAC systems.

• Stepper motors are used in robotics and automation.

• Servo motors are used in precision control systems such as robotics and CNC machines.

• Linear motors are used in high-speed transpor
