Understanding the temperature limits of your GC column is essential for maintaining optimal performance and preventing permanent damage. Exceeding the recommended temperature range can affect the stationary phase, reduce column efficiency, and compromise analytical results. Always check your column’s temperature specifications and consult your technical sales consultant if you are unsure.
Protect your GC column. Know its temperature limits!
The maximum temperature of a GC column depends on its stationary phase, film thickness, and manufacturer’s specifications. Polar columns are generally more susceptible to thermal degradation, which can lead to excessive column bleed, peak tailing, and reduced separation efficiency.
To ensure optimal performance and extend column life, always operate within the recommended temperature limits and use high-temperature-compatible accessories. Proper gas management is also essential to prevent oxygen and other contaminants from damaging the column, especially at elevated temperatures

Consistent mobile-phase preparation is essential for reliable HPLC results. Use an appropriate buffer within its effective pH range and clearly specify its composition and concentration. Add organic solvent to the aqueous phase to minimize precipitation, and properly filter and degas the mobile phase. Before changing solvents, flush the system to prevent buffer precipitation and damage. Avoid using the final remnants of mobile-phase bottles, as evaporation can alter their composition.
The HORIBA LAQUA 200 Series is a range of rugged handheld water quality meters designed to measure pH, ORP, dissolved oxygen, conductivity, resistivity, salinity, TDS, and temperature. With purpose-built configurations, users can select the parameters they need without paying for unnecessary channels. The meters support internal data logging, calibration against recognized standards, and reliable operation in both laboratory and field environments. The 210 models store 500 data points for routine testing and spot checks, while the 220 models store 1,000 data points and include an RS-232 interface for direct data transfer to a PC or printer. The series is suitable for applications including environmental monitoring, drinking water and wastewater treatment, industrial process control, laboratory QC, aquaculture, and food, beverage, and pharmaceutical testing.
