HPLC + DC ???

[Basil]

Anyone knows what does it means ???...

A costumer said that our sample fails because didn't pass the HPLC+DC control quality....

Is that a new kind of detector for HPLC or Hyphenated technic ?

Thanks in advance...

Basil

Hi Basil

Why not just ask the customer ?!!!!!

Is your customer by any chance German speaking? DC could be the German abbreviation for "Thin Layer Chromatography" (Duennschichtchromatographie)

cheers,

Robert

Thanks rhaefe.... Our costumer is from Germany....

It will be also possible a : High-Performance Liquid Chromatography with Dielectric Constant Detection but I have never used and know if our costumer has one...

Thanks Peter also, but our Quality Control departmen does not want to ask to the costumer, ... strange but real....

Thanks again

Basil,
Your QC probably doesn't want to lose face with the customer.
"Yeah.Course we know what a DC detector is!"......
"You know that supplier? - they don't know what a DC detector is"....

Just for the record,Basil, I wouldn't have a clue either.

Could it be "detector of conductivity"?

Basil,

DC could be DC amperometric detection or perhaps more likely differential calorimetry, a thermal method sometimes used to assess purity of high purity samples (more often called DSC, diferential scanning calorimetry).
