direct insertion probe (DIP)
The direct insertion probe is a shaft having a sample holder at one end. The probe is inserted through a vacuum lock to place the sample holder near to the ion source. The sample is vaporized by heat from the ion source or by heat from a sepa- rate heater surrounding the sample holder. The sample molecules are evaporated into the ion source where they are then ionized as gas-phase molecules.
