Thermo Fisher Scientific this week announced a program allowing researchers to trade in their single quadrupole or ion trap mass spectrometers for a Thermo Fisher linear ion trap instrument.
Under the program, researchers will be able to upgrade to a Thermo Fisher LTQ XL or the newly launched LTQ Velos. The company is also offering a free electron-transfer dissociation technology upgrade with the purchase of an LTQ XL or LTQ Velos.
