This is our YL6500 GC. Now, it's discontinued and we provide a new GC, ChroZen GC.

Hi, Thanks for your inquiry. The detector recommendation would differ depending on the sample matrix, concentration, etc. You can have a look at the site: webbook.nist.gov/cgi/cbook.cgi?ID=C80568&Units=SI&Mask=FFFF#Mass-Spec For more details, you can contact us at export@youngincm.com

@@YOUNGINChromass Thank you very much your information was very helpful🙂🙂

Thanks for your interest. The flow rate differs depending on the model from 12~120 L/min.

@@YOUNGINChromass compared to your competitors its too low

Found it: Asparagine and Glutamine are converted directly into their corresponding acids, Aspartic acid and Glutamic acid, so cannot be directly quantified.

Hi, thanks for your interest. I'm afraid we don't. The highest flow rate we provide is up to 120L/h.

Hi, thanks for your interest. It varies depending on the configuration. You can send an inquiry to export@youngincm.com .

Hi, thanks for your interest in our Sugar Analyzer. The columns used in this application are the Carbohydrate and NH2 columns, which are the ligand exchange column and normal phase column. It is commonly recommended to use these columns for sugar analysis. If you have any other inquiries, please contact export@youngincm.com.

Hi, If you send a request to export@youngincm.com , we can guide you for the details.

Hi, thanks for your interest. We have several application notes for vitamin analysis. eng.youngincm.com/goods/read.php?M2_IDX=18457&SC_ALL=&SC_SC1_IDX=400&SC_SC2_IDX=1064&SC_SF_IDX=Array&SC_SM_IDX=&SC_TYPE=&SC_WORD=&SC_TI_IDXS=&SC_PA_LEN=&SC_LIST_TYPE=&SC_BOOKMARK=N&SP_CODE=2112G4I7 You can click the link above and find what you're looking for at the bottom of the application note section.

Dear Sir, I suppose you have a problem with low column flow rate during the column conditioning due to the leak. When GC detects the column flow rate is lower than the set point while the oven temperature is running, GC will cool down the temperature to avoid column damage. You must find out where the leak problem occurs in order to solve this problem. For further inquiry, please contact export@youngincm.com

Hi, the most common temperature programming for column conditioning is shown in 3'18"~ 3'30". But it differs depending on columns. The best way is to follow the instruction in your column box. (The column conditioning guide should be included in your column box.)
