GC and GCMS webinars - Week 11

<h3><strong>1. Gas Source</strong></h3>
<p><strong>Helium</strong> is becoming increasingly expensive with reports of its price having doubled in some regions between 2013 and 2015. Added to its increased price, supply cannot be ensured in certain regions which is increasing the number of labs looking to change to hydrogen.</p>
<p><strong>Hydrogen generator:</strong> A hydrogen generator providing carrier grade hydrogen (99.9999%) such as the Peak Scientific <a href="https://www.peakscientific.com/products/hydrogen/"><strong>Precision Hydrogen Trace</strong></a> is recommended as a safe source of hydrogen that will ensure prolonged column life and the highest quality of analysis.</p>
<p><strong>Supply tubing:</strong> Supply of hydrogen should be provided through new stainless steel or analytical grade copper tubing. It is important to change the tubing that was previously used to supply helium to the GC, since over time, deposits can build up on the inside of the tubing which hydrogen will strip out, causing higher background signal for a longer period of time.</p>
<h3><strong>2. Hydrogen Safety</strong></h3>
<p>Safe use of hydrogen: Since Hydrogen is an explosive gas, it is essential that health and safety in the lab is not compromised and many labs will have restrictions on the use of hydrogen cylinders in the lab.</p>
<p><strong>LEL:</strong> The lower explosive level (LEL) of hydrogen is 4% in air. Therefore a leak of hydrogen from a cylinder containing around 8000L hydrogen into a well vented laboratory has the potential to reach the LEL very quickly without warning and could create an explosive atmosphere. Added to concerns about large gas leaks, is the cumbersome nature of cylinders which must be moved when replaced, again posing a potential health and safety hazard.</p>
<p><strong>Gas Generator:</strong> A Peak Scientific Precision hydrogen generator is an ideal source of hydrogen gas, capable of supplying multiple GCs with UHP hydrogen for carrier gas and detector gas, whilst containing a very low volume of gas (less than 0.3L) at a low pressure. Precision hydrogen generators have a number of safety features that will detect any internal or external leaks between the generator and GC and will shut down the generator accordingly.</p>
<p><strong>Leak detector:</strong> Peak also offer an in-oven hydrogen detector that will shut down the generator if a significant hydrogen leak is detected within the GC oven.</p>
<h3><strong>3. Hardware</strong></h3>
<p>It is important to check the recommendations from  your  GC  manufacturer  regarding  use  of  hydrogen  carrier  gas  in  your  GC.  Each  manufacturer  will  have  tested  their  GCs  for  use  with  hydrogen  and  may  have  specific  recommendations  depending  on  the  model  that   you   are   using.   Hardware   changes,   if   required,  are  most  likely  to  need  to  be  made  on GC-MS systems.</p>
<p><strong>Vacuum Pump:</strong> If you are using a GC-MS, it is important  to  ensure  that  your  vacuum  pump  is  efficient  enough  to  maintain  the  vacuum  in  the  source.  Pumping  efficiency  is  reduced  for  lighter  molecules,  so  check  the  guidelines  from  your  GC  manufacturer  to  ensure  that  your pumping system can cope with hydrogen carrier  gas.  If  you  are  purchasing  a  new  GC-MS system, make your supplier aware that you plan  to  use  hydrogen  carrier  gas  so  that  the  correct vacuum pump is supplied.</p>
<p><strong>Ion  Source:</strong>  Depending  on  the  manufacturer  of your GC-MS, it is possible to get hydrogen upgrade kits, or replacement components for the  ion  source  which  will  improve  sensitivity  when  using  hydrogen  carrier  gas  for  analysis  of  certain  compounds.  If  you  are  purchasing  a  new  GC-MS  system,  consult  your  supplier  regarding  which  ion  source  will  be  supplied  with   the   GC-MS   to   avoid   extra   cost   and   downtime at a later date.</p>
<h3><strong>4. Consumables</strong></h3>
<p><strong>Column:</strong>  For  standard  GC,  there  is  very  little  that  needs  to  be  changed  when  switching  from  helium  to  hydrogen.  By  using  a  method  translation  software,  you  can  simulate  the  effect  of  changing  carrier  gas  on  carrier  gas  pressure and oven ramp rates so that you can produce   a   revalidated   method.   Depending   on  your  GC  method  parameters,  it  may  not  be  necessary  to  change  to  a  narrower  bore  column,  unless  the  inlet  pressure  becomes very  low  in  the  translated  method,  however  there  are  benefits  to  using  a  narrow  bore  column,  which  the  properties  of  hydrogen  carrier gas facilitates. By moving to a narrower bore column, the number of theoretical plates is  increased,  giving  potential  for  improved  efficiency and better sample separation.</p>
<p><strong>Inlet:</strong> Inlet liners should be changed regularly to   ensure   that   the   system   stays   free   of   contaminants.  When  running  samples  with  hydrogen   carrier   gas,   tapered   liners   are   recommended  since  these  minimise  contact  with  the  gold  seal  in  GC  systems  that  have  a  gold seal.</p>
<p><strong>Septa:</strong>  Changing  inlet  septa  is  a  routine  part  of GC maintenance and should be conducted regularly  to  avoid  leaks  in  the  system  and  prevent contamination.</p>
<h3><strong>5. Method</strong></h3>
<p>It is essential to confirm that your method can be  used  with  hydrogen  carrier  gas.  If  you  are  using any regulated methods (eg. EPA, ASTM), first  check  what  carrier  gases  are  permitted.  If  hydrogen  is  permitted,  then  research  your  method(s) of interest to see whether there are any application notes on this method?</p>
<p><strong>Method     translation     software:</strong>    Method     translation software is available from a variety of  sources  and  can  be  used  to  calculate  GC  settings  when  using  hydrogen  carrier  gas.  This will enable you to optimise your method and  explore  column  options  prior  to  actually  setting  the  system  up  with  hydrogen  carrier  gas.</p>
<p><strong>Use  of  chlorinated  solvents:</strong>  Formation  of  hydrochloric acid (HCl) through reaction of Cl and  H₂  is  often  cited  as  a  potential  problem  for  GC  and  GC-MS  when  using  hydrogen  carrier  gas  since  HCl  will  damage  the  GC  system.  Reactions  between  H₂  carrier  gas  and  analytes  or  solvent  will  normally  occur  in the inlet, so reducing the residence time of your  sample  in  the  inlet  is  key.  Use  of  pulsed  splitless or pulsed split injection can help with reducing residence time of sample in the inlet, reducing the opportunity for formation of HCl or  reactions  between  hydrogen  and  analytes  occurring.</p>
<p><strong>Inlet   temperature:</strong>   Using   the   lowest   inlet   temperature   possible   for   the   method   will   reduce  the  potential  for  reactions  between  solvents, analytes and hydrogen.</p>
<h3><strong>6. System setup</strong></h3>
<p><strong>Column conditioning:</strong> When setting up a new GC system with hydrogen carrier gas, you will need  to  condition  the  column.  Ensure  that  the end of the column is outside the GC oven when  you  condition  the  column  to  prevent  a  build-up  of  hydrogen  within  the  GC  oven  as  this could present a risk of explosion.</p>
<p><strong>Ion source bakeout:</strong> If you are setting up a GC-MS, it is common to see performance problems when  tuning  the  system,  or  running  samples  shortly after setting up with hydrogen carrier gas. This can be seen as high hydrocarbon-like background  and  a  high  m/z  29  peak.  Baking  out  the  ion  source  can  quickly  resolve  these  issues, with background settling down after an overnight back-out. Details of how to bake out your MSD can be found manufacturers’ guides and webinars covering use of GC-MS systems with hydrogen carrier gas.</p>
<h3><strong>7. Performance checkout</strong></h3>
<p><strong>Signal to noise:</strong> Signal to noise is often reduced when  comparing  results  of  samples  run  with  helium  compared  with  hydrogen  (2-5  times  depending  on  the  system).  The  reduction  in  signal to noise can be improved by using SIM detection on a single quadrupole system.</p>
<p><strong>Fragmentation patterns:</strong> If ion ratios change, it is likely that too much Hydrogen is present in the ion source. This problem can be mitigated by   reducing   the   column   ID   and   therefore   reducing   the   carrier   gas   flow   rate,   thus   reducing the volume of Hydrogen entering the ion source.</p>
<p><strong>Peak  tailing:</strong>  Polar  components  may  suffer  more   significantly   from   Peak   tailing   when   using  hydrogen  carrier  gas.  After  baking  out  the ion source, peak tailing should reduce and will normally reduce for most compounds after a few days.</p>
<p><strong>Background:</strong> A  few  days  following  changing  carrier gas, the background signal should drop to a consistent level.</p>
