Ralf Leidner - Fort Collins CO, US
Murphy Pickard - Broomfield CO, US
Assignee:
Hach Company - Loveland CO
International Classification:
G01N 1/10
US Classification:
7386301
Abstract:
An aspect provides a method of autonomously flushing a process instrument, including: providing a sample fluid to a measurement chamber of the process instrument; providing a measurement agent to the sample; and responsive to a predetermined flushing condition, flowing measurement agent free fluid through the measurement chamber. Other aspects are described and claimed.

Detection Of Oxidant In Seawater

View page
US Patent:
20210341418, Nov 4, 2021
Filed:
May 1, 2020
Appl. No.:
16/864675
Inventors:
- Loveland CO, US
Ralf Leidner - Fort Collins CO, US
International Classification:
G01N 27/416
G01N 27/48
G01N 27/30
G01N 27/38
Abstract:
An embodiment provides a method for measuring total oxidant in a seawater sample, comprising: forming a seawater solution and a formed iodine by introducing a buffer and an iodide reagent to a seawater sample, wherein the seawater sample contains an amount of oxidant; placing the seawater solution in a measurement device, wherein the measurement device comprises a boron doped diamond working electrode reacting with the seawater solution and the formed iodine, wherein an electrochemical process reduces the formed iodine to iodide; and measuring the amount of total oxidant in the seawater sample by measuring, using the measurement device, an amount of iodide in the seawater sample. Other aspects are described and claimed.

Liquid Mixing

View page
US Patent:
20200338560, Oct 29, 2020
Filed:
Apr 29, 2019
Appl. No.:
16/397259
Inventors:
- Loveland CO, US
Cory Scott Miller - Loveland CO, US
Ralf Leidner - Fort Collins CO, US
Robert Allen Luther - Fort Collins CO, US
International Classification:
B01L 3/00
Abstract:
An embodiment provides a device for mixing at least two reagent fluids, the mixed at least two reagent fluids being used for the measurement of a chemical attribute of a sample, including: a housing; at least two inlet ports, each to receive fluid in a premix state; an outlet port to dispense fluid in a postmix state; and a surface of a lumen for mixing, located within the housing, having a predetermined length, wherein the surface of the lumen is located between the at least two inlet ports and the outlet port, wherein the at least two inlet ports transition into the surface of the lumen, wherein the predetermined length is of a length allowing for sufficient mixing of the fluids received by the at least two inlet ports, wherein the surface of the lumen comprises at least one anti-siphoning element and a plurality of weirs to create a disturbance of a fluid contained therein, wherein the at least two fluids each comprise a reagent for a measurement of a chemical attribute of a sample. Other aspects are described and claimed.

Insertion Mount Device

View page
US Patent:
20150090054, Apr 2, 2015
Filed:
Sep 29, 2014
Appl. No.:
14/499704
Inventors:
- Loveland CO, US
Ralf Leidner - Fort Collins CO, US
International Classification:
G01D 11/30
G01N 33/18
US Classification:
738665
Abstract:
Described herein is an insertion mount, including a threaded cylindrical mount with a hollow inner diameter and a lengthwise slot cutout for receiving a probe; and a drive assembly further comprising a drive nut, wherein the drive nut has threads that engage the threaded outer diameter of the threaded cylindrical mount which allows the drive nut to be moved the length of the cylindrical mount by screwing the drive nut of the drive assembly onto the threads of the threaded cylindrical mount.
