SUMMARY OF GAS SOURCES AND INFORMATION
Peak Scientific Instruments Ltd
WHAT INFORMATION DO I NEED ABOUT LC/MS GAS REQUIREMENTS AND WHERE WILL I FIND IT?
• Consult the LCMS manufacturer/gas supplier
• Confirm the gas requirements (nitrogen, air, other?)
• Confirm the required specifications for flow and pressure
• Are there any other special gas requirements?
• Consult the LCMS site prep guide if available
• Is there a defined level of noise acceptable in the laboratory
NOW YOU HAVE A GOOD IDEA OF WHAT YOU REQUIRE.
WHICH GAS MANAGEMENT SYSTEM WILL BE BEST FOR MY LAB AND MY LCMS SYSTEMS?
•In house gas
•Liquid Nitrogen Dewar
•Cylinder gas
•Industrial gas generator
•Laboratory gas generator
SO HOW DO I DECIDE WHICH ONE?
Peak Scientific Instruments Ltd
Peak Scientific Instruments Ltd
WHAT ARE THE DECISIONS I NEED TO MAKE?
“What is right for the application and your lab?”
• Stand alone gas generator for each LCMS in lab (using existing house air)?
• Stand alone gas generator with separate external air compressor?
• Laboratory gas generator with built in compressors for each LCMS ?
• How many LCMS systems will require gas?
• Is this likely to change (increase) in the near future?
• If more than one LCMS, will they all have the same gas requirements?
• Are they located in the same area/laboratory?
• What are the distances from generator to LCMS?
• Are there any special Health & Safety Regulations to be considered?
NOW YOU KNOW WHAT DECISIONS NEED TO BE MADE!
Peak Scientific Instruments Ltd
USING EXISTING HOUSE AIR SUPPLY
. CAUTION!• If you select a gas generator for use with an existing house air
supply, make sure the air is of good quality and has the capacity to supply the correct flow and pressure to the gas generator.
• You must also ensure that the air supply will not contaminate the generator or the LC/MS System – it must be
Clean, Dry and Oil – free
• The generator should only ever be connected to a clean, dry and oil-free source of compressed air. If in any doubt, do not use this source of air.
• A regulated minimum pressure of 120 psig is required for the generator to operate correctly.
NB. Contaminated air supplies are a common source of problems!
Peak Scientific Instruments Ltd
USING EXISTING OR NEW PIPEWORK?
.• Is the generator to be connected to existing or new pipework?
• If you plan to use existing pipework, has it been pressure/leak tested by a competent, qualified technician?
• Can you guarantee that it is clean and free of contaminants?
• What is the i.d/o.d of the tubing?
• Do you know which material the tubing is made from?
• If in any doubt, do not use this existing pipework – use new tubing of the correct internal diameter and material type.
NB. Contaminated pipework is a common source of problems!
CAUTION!

WHICH GAS MANAGEMENT SYSTEM WILL BE BEST FOR MY LAB AND MY LCMS SYSTEMS?
• In house gas x
• Liquid Nitrogen Dewar x
• Cylinder gas x
• Industrial gas generator √
• Laboratory gas generator √
So if I choose a generator, what are the options and how do I decide which is best for me?
Peak Scientific Instruments Ltd
SO HOW DO I DECIDE WHICH GENERATOR?
Let me show you five gas generator possibilities:
Single LC/MS gas generator
1. With internal (built-in) compressors2. With separate air compressor system3. With separate air system and possibility to upgrade
Multi LC/MS gas generator
4. With separate air system and individual nitrogen generators (one for each LCMS system)5. With separate air system and one high capacity nitrogen generator (enough to supply all systems running at full
flow simultaneously)

HOW MUCH WILL A GAS GENERATOR COST TO RUN?
Peak Scientific Instruments Ltd
Peak Scientific Instruments Ltd
THE DESIGN OF LC/MS SYSTEMS CONTINUES TO EVOLVE VERY RAPIDLY AND THEY ALL HAVE DIFFERENT GAS REQUIREMENTS
Scientists are continually looking for
•Better qualitative and quantitative performance
•More sensitivity
•Improved resolution
•Better productivity and efficiency
•New LCMS models are introduced every year
This often means Peak Scientific needs to produce a new generator to match the needs of the latest LCMS system
Peak Scientific Instruments Ltd
THE PEAK SCIENTIFIC APPROACH TO GAS GENERATORS FOR LC/MS
• Which LCMS manufacturer and model?
• Designs and specifications vary from model to model and so do the gas requirements!
• What is the type of instrument?
• Single or triple quad, TOF etc...?
• What is the application – ESi or APCi or both?
In summary –
The Peak Scientific approach is to design and manufacture bespoke generators which exactly match the gas requirements of the mass spectrometer application
Peak Scientific Instruments Ltd
• Bespoke gas generators for the analytical instrument industry
• Mainly supplying generators for LCMS & GC instruments
• So Peak is a niche market supplier to those OEMs
• Peak manufactures high purity nitrogen, hydrogen and zero air generators as well as some others for TOC, purge gas and calibration gas applications
• Our main focus is on supplying quality products backed up with worldwide service and support
