Context: Analytical HPLC was carried out using one of the following methods:
Method A: Waters pump (600), Waters differential refractometer (410), RI detector settings: scale factor = 20, sensitivity = 2, oven temperature = 35 oC. Phenomenex Luna C18(2), 4.6 x 150 mm, 5 µm; Isocratic MeCN/H2O (30/70); 1 mL/min; injection volume: 20 µL.
What dose " Isocratic" in the second line from the bottom. Does it mean equal?

It means \"equal\" in the sense that they stay the same. Look at the following:
Isocratic Elution
Refers to an HPLC separation where the mobile phase composition stays the same during the entire analysis. Isocratic separations are the opposite of GRADIENT ELUTION separations.
Upchurch Scientific - Glossary
... Gradient Elution An HPLC procedure where the composition of the mobile phase changes
during the separation; opposite of ISOCRATIC ELUTION where the mobile ...
