Required materials
•
Chemical-resistant, powder-free gloves.
•
Appropriately sized glass vessels in which to completely immerse components when
cleaning. Use only glassware not previously cleaned with surfactants.
•
HPLC-grade (or better) methanol.
•
HPLC-grade (or better) water.
•
Formic acid.
•
Ultrasonic bath.
•
Source of oil-free, inert gas (for example, nitrogen) for drying (air-drying optional).

Warning:
To avoid personal contamination with biohazards or toxic materials, and to avoid
spreading contamination to uncontaminated surfaces, wear clean, chemical-resistant, powder-free
gloves when working with the ion block components.
Warning:
To avoid injury, work with extreme care. Use a fume hood, and suitable protective
equipment. Formic acid is extremely corrosive and toxic.
