|
1. Low maintenance. |
|
1. High maintenance. Must
replace seals and check valves. |
| 2. Fits easily in hood. |
|
|
2. Fits easily in hood. Except
for larger systems that require multiple parts and not easy to move
around. |
|
2. Large and difficult to move
around. |
| 3. Simple to use. |
|
|
3. Simple to use. |
|
3. More complicated to use
than RT Scientific systems. |
| 4. One system will separate
sample sizes of milligrams to multi-grams. |
|
|
4. One must buy several
different systems to do separation of milligrams to multi-grams. |
|
4. One system will separate
samples sizes of milligrams to multi-grams. |
| 5. No pulsating. This gives
better separation. |
|
|
5. No pulsating. |
|
5. Pulsating. This reduces the
efficiency of your separation. |
| 6. Capable of doing true
gradients, not step gradients. |
|
|
6. Will not do true gradients
unless you buy more expensive systems with limited solvent use. |
