GPC/SEC/DSV Sample Analysis Service

Dear Valued Customers:

We are pleased to announce the creation of a new HMJ GPC/SEC/DSV sample analysis service platform for our polymer/biopolymer customers that is differentiated by expertise, reliability, and cost.  Our most innovative offering is a set of 9 TDAmax (Triple/Tetra) GPC/SEC systems and a set of 4 DSV systems that is capable of providing 3-day turnaround time for routine samples.  

The set of GPC/SEC instruments includes:

Routine GPC Analysis:     Instrument for nonpolar polymers (e.g., PS in THF)
                                            Instrument for neutral aqueous polymers (e.g., PEO in Water)
                                            Instrument for standard FIPA-XS (e.g., PP in THF)

Non-Routine GPC Analysis:    Instrument for polar polymers (e.g., PAN in DMF)
                                                    Instrument for cationic polymers (e.g., PEI in Acetic Acid)
                                                    Instrument for proteins (e.g., BSA in PBS)
                                                    Instrument for special FIPA-XSAI (e.g., ICP/EPR in Tetralin)
                                                    Instrument for method development

The set of DSV instruments includes:    HTDSV for Polyolefins (e.g., PP in Decalin)
                                                                     DSV for Polyamides (e.g., Nylon in Formic Acid)
                                                                     DSV for PVC (e.g., PVC in THF or Cyclohexanone)
                                                                     DSV for PET (e.g., PET in 60/40, Phenol/TCE)
                                                                     DSV for method development

The range of applications offered by these 13 instruments probably covers 80% of typical customer needs.  Application information is provided in our Learning section of our website so that customers can choose the correct method for their samples.  More difficult or research-type samples can be handled on a method development basis.  For more information and sample submission procedure, please browse the Services section of our website.
