Troubleshooting

WARNING

Before performing any procedures in this chapter, please read and observe
the safety requirements in the “Isolera Installation and Safety” document
(P/N 411828). Failure to follow those requirements may result in personal
injury and/or equipment damage. If the system has been damaged and
does not function properly, shut it down and contact Biotage 1-Point
Support immediately.

6.1 Contact Biotage 1-Point Support

If your problem persists, or for assistance at any time during troubleshooting, contact Biotage
1-Point Support. See contact details on page 7-1.

6.2 Accessories and Spare Parts

A condensed list of accessories is available on page 5-1. For a complete list, please contact you
local representative.

A list of spare parts is available at www.biotage.com.

6.3 Fraction Collector-Related Problems

Problem

Possible Causes

Solutions

1. The collection arm

does not position
correctly over each
collection vessel.

a. Misaligned rack(s).

Ensure that the rack(s) is/are aligned correctly.

b. Wrong rack type

selected in the
software.

Ensure that you select the correct rack type when
setting up a method; see “Create, Open, and Edit
Methods” on page 4-2.

c. Incorrect rack

parameters. (Only if
using a user-defined
rack type.)

Ensure that the correct rack parameters have been
entered for the used rack type; see “Administrate
the Rack List” on page 2-5.

d. The collection arm is

obstructed.

Remove any obstacles that obstruct or restrict arm
movement.

e. Improper calibration

of the collection arm.

Calibrate the collection arm; see “Calibrate the
Fraction Collector” on page 3-13.

2. Dripping needle

and/or inconsistent
dispensing
volumes

.

Dirty collect valve.

Clean the collect valve with methanol or a similar
solvent using the Collect Valve Clean Wizard; see
page 3-13.
