What is ICP-MS Used For?

The Inductively Coupled Plasma–Mass Spectrometer (ICP-MS) is one of the most powerful and sensitive analytical instruments available for elemental analysis. Commonly known simply as ICP-MS, it is used to detect trace and ultra-trace concentrations of metals and certain nonmetals across a wide variety of sample types—including those we encounter in our daily lives.

What Is ICP-MS Used For?

ICP-MS plays a critical role in both research and industry because of its exceptional sensitivity, accuracy, and multi-element detection capabilities. It can measure metal concentrations down to parts-per-trillion levels, making it indispensable for environmental, clinical, and materials analysis. Common applications include:

• Detecting lead and heavy metals in toys and consumer products
• Monitoring metals in fly ash and industrial waste
• Testing landfill leachate for contamination
• Analyzing drinking water and wastewater for trace metal pollutants
• Assessing medical devices for biocompatibility and safety
• Supporting pharmaceutical drug development and packaging validation
• Testing cannabis and hemp products for toxic metal residues

Understanding Harmful Metal Concentrations

Many elements detected by ICP-MS, such as lead, cadmium, and mercury, are toxic even at trace levels. Determining the concentration of these elements—whether they occur naturally in a sample or are introduced through manufacturing—is essential to protecting both human health and the environment. Thanks to advancements in ICP-MS technology, laboratories today can monitor contaminants with unprecedented precision, helping ensure compliance with safety regulations and environmental standards.

Getting Started with ICP-MS

Setting up an ICP-MS laboratory requires careful planning and consultation with experienced OEM representatives and technical specialists. Several infrastructure and operational components must be considered for reliable, accurate results:

• Chemicals: High-purity water and acids to minimize contamination
• Calibration Standards: Certified standards for accurate quantitation
• Safety: Proper waste containment, ventilation, and chemical handling
• Exhaust Systems: Adequate ventilation to remove gases and vapors
• Autosampler Isolation: Controls to prevent airborne contaminants from affecting results
• Maintenance: Regular cleaning and servicing of the instrument and vacuum pump
• Power Management: Surge and UPS protection to ensure stable operation
• Instrument Gases: Reliable supply of Argon, Collision, and Reaction Cell gases
• Support Equipment: Acid digestion systems, analytical balances, and clean benches

Essential ICP-MS Consumables

Having the correct consumables on hand is key to maintaining consistent instrument performance and data reproducibility. Common ICP-MS consumables include:

• Torches: Deliver the plasma used for ionization
• Spray Chambers: Aid in sample aerosol formation and transport
• Nebulizers: Convert liquid samples into a fine mist for efficient plasma introduction
• Skimmer and Sampler Cones: Direct ions from the plasma into the mass spectrometer
• Peristaltic Pump Tubing: Maintains consistent sample flow to the nebulizer
