HPLC Injection Problems

Troubleshooting Advice

I am running an isocratic method with a 250 x 4.6 mm, 10 µm particle column at 1 mL/min with a 20% acetonitrile (ACN)/buffer mobile phase. I dissolve my sample in ACN and inject. Normally my compound of interest comes out at 7.7 min. I switched to a 250 x 4.0 mm column, keeping everything else the same, but now I see a distinct hump on the front of the peak. Is this another compound or am I doing something wrong?

Buffer Preparation

Troubleshooting Advice

I use trifluoroacetic acid (TFA) to adjust the aqueous portion of my HPLC mobile phase to pH 2.5. Even with careful pH adjustment, I see changes in retention when I prepare each new batch of mobile phase. Retention seems to be consistent within a batch, but batch-to-batch variability concerns me. Can you shed any light on this problem?
