FAQs of Gel Permeation Chromatography(Gpc):
Q: How does the refractive index detector (RID) enhance GPC analysis?
A: The refractive index detector in the GPC system provides highly accurate detection of sample components, enabling precise molecular weight determination and polymer characterization, especially effective for substances with limited UV absorption.
Q: What is the recommended process for preparing samples for analysis with this GPC system?
A: Samples should be dissolved in a compatible eluent, ensuring a maximum volume of up to 5 mL. Its important to filter the solutions to remove particulates before injection into the stainless steel column to maintain optimal system performance and accuracy.
Q: When should the maximum pressure limit of 400 psi be considered during operation?
A: The pressure limit is critical when selecting columns and operating flow rates. Exceeding 400 psi may risk damage to the column or pump system; therefore, monitor pressure using the digital display and adjust flow rates to maintain safe operation within specifications.
Q: Where can this GPC detection system be used effectively?
A: The equipment is ideally suited for laboratory environments dedicated to quality control, polymer research, molecular weight measurement, and is widely used by manufacturers, exporters, and suppliers in India for analytical applications.
Q: What benefits does the corrosion-resistant design offer for long-term laboratory use?
A: Constructed using SS 304 stainless steel and borosilicate glass, the system is highly resistant to chemicals and corrosion. This extends equipment lifespan, reduces maintenance requirements, and ensures consistent performance under prolonged laboratory conditions.
Q: How can data be output and analyzed from this GPC equipment?
A: Data can be transferred quickly via USB or RS232 ports to computers running Windows-based chromatography software. This setup allows efficient analysis, archiving, and reporting of results for further research or quality assurance.
Q: What safety features are incorporated in the system to ensure reliable operation?
A: Key safety features include over-temperature protection and a main fuse, safeguarding both users and equipment from thermal or electrical hazards during routine laboratory work with heating capacity up to 600 W.
