HP-INNOWax 19091N-133I

Question

HP-INNOWax column 19091N-133I cannot be selected during method development, is it possible to select 19091N-133ILTM (ILTM format) as an alternation choice?

HI Gordon, 
 I'm not sure what you mean, but LTM-type columns are only for the Low-Thermal Mass instruments and cannot be used in any standard GC. There is a 30 m x 0.25 mm, 0.25 &micro;m HP-Innowax on a 5 inch cage with part number 19091N-133ie. 
 Regards, 
 Norbert

The Tmax for 19091N-133ie is 260 &deg;C, NOT 445 &deg;C. The difference to 19091N-133i (Tmax also 260 &deg;C) is only the cage diameter 5 inches instead 7 inches. 
 I cannot suggest anything instrumental here as this is the columns and supplies forum, if this is about settings in a GC, please pose this question in the GC forum. Thank you
