Looking to optimize your HPLC performance? Today, we’re sharing tips on VARIABLE RETENTION TIME 💡 A smooth workflow starts with identifying potential causes! 𝐃𝐢𝐚𝐠𝐧𝐨𝐬𝐢𝐬: tR too short: 🔵 Leakage 🔵 Flow of eluent A (water) too low 🔵 Column temperature fluctuations tR too long: 🔵 Flow of eluent B too low 🔵 Column problem 🔵 Air trapped in pump head 🔵 Column temperature fluctuations 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬: 🔵 Check the flow rate at the outlet with a graduated vessel 🔵 Open the purge valve and check the flow rate of each pump head 🔵 Check the pressure and compare with previous measurements values 🔵 Purge the system with 100% A or B and higher flow rates 🔵 Replace precolumn 🔵 Renew and adjust the solvents 🔵 Degas eluents and dissolve sample in mobile phase A well-running system means better results! Try these tips and let us know how they work for you! More insights coming next week. 🥳 #thinklc #thinkknauer #troubleshooting #hplc
