Gpc 80md

Manufactured by Shimadzu

Sourced in Japan

The GPC-80MD is a gel permeation chromatography (GPC) system designed for the analysis of molecular weight distribution in polymer samples. It features a solvent delivery pump, an auto-injector, and a refractive index detector. The GPC-80MD is capable of separating and analyzing polymers based on their molecular size.

GPC was performed on a Prominence Liquid Chromatography system (Shimadzu) equipped with a RID-10A refractive index detector and three Shimadzu Shim-pack columns in series (GPC-8025D, GPC-805D and GPC-80MD) at 60 °C. 0.05 M LiCl in DMF was used as the mobile phase at a flow rate of 1.0 mL/min. Sample concentrations of 10 mg/mL were used with an injection volume of 50 µL. MW characteristics were determined with reference to a conventional calibration with PEG standards (Polymer Standards Service GmbH; molar mass at peak maximum (M_p) = 194 to 969 kDa).

Gas chromatography (GC) was performed on a Shimadzu GC-2010 gas chromatograph (Kyoto, Japan). Proton nuclear magnetic resonance spectroscopy (¹H NMR) was conducted on a Bruker Avance III HD 600 MHz spectrometer (Billerica, MA, USA). GPC was performed using a Shimadzu Prominence liquid chromatography (LC) system (Kyoto, Japan), fitted with a differential refractive index detector (Shimadzu, RID-20A) and two Shimadzu columns in series (GPC-80MD and GPC-804D). Modulated differential scanning calorimetry (MDSC) and thermogravimetric analysis (TGA) were conducted using TA Instruments (New Castle, WY, USA) DSC 250 and TGA5500, respectively. Ultraviolet-visible (UV-vis) spectrophotometry was performed on an Evolution 260 Bio spectrophotometer, and temperature-controlled using a single-cell Peltier system (Thermo Scientific, Waltham, MA, USA). Fluidised-bed spray coating was conducted using a benchtop Mini Coater/Drier 2 (Caleva Process Solutions Ltd., Dorset, UK).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
