摘要： The present invention provides a new design for high capacity stationary phases for dianion selective ion chromatography. The stationary phases include one or more layers which are products of condensation polymerization. Multiple components are of use in forming the first polymer layer and the condensation polymer structure, thereby providing a stationary phase that can be engineered to have a desired property such as ion capacity, ion selectivity, and the like. Exemplary condensation polymers are formed by the reaction of at least one polyfunctional compound with at least one compound of complimentary reactivity, e.g., a nucieophilic polyfunctional compound reacting with an eiectrophilic compound.

摘要： Methods, devices, and systems for ensuring state synchronization between two communicating nodes which use a state based stream cipher. Two nodes in a communications network set up two one way links between them, one from a first node to a second node and one from the second node to the first node. Each link has its own resources at each node and each link has its own counter at each node. When communicating, the transmitting node encrypts data using a state based stream cipher and a key shared by both nodes along with an encryption state. The transmitting node transmits the encrypted data to the receiving node along with a counter value corresponding to the link used for the transmission. The receiving node, after receiving the encrypted data, confirms the received counter value with its own counter for that link. After confirmation, the receiving link decrypts the encrypted data using the state based stream cipher, the shared key, and the encryption state. The two nodes are state synchronized such that each node, when using the state based stream cipher and the same key, produce the same cipher stream. In the event synchronization is lost, on possible resynchronization procedure involving a 4 part handshaking process between the two nodes and which involves an exchange of nonces (also referred to as markers) may be used.
摘要翻译：用于确保使用基于状态的流密码的两个通信节点之间的状态同步的方法，设备和系统。通信网络中的两个节点在它们之间建立两个单向链路，一个从第一节点到第二节点，一个从第二节点到第一节点。每个链路在每个节点都有自己的资源，每个链路在每个节点都有自己的计数器。当通信时，发送节点使用基于状态的流密码和由两个节点共享的密钥以及加密状态来加密数据。发送节点将加密数据与对应于用于发送的链路的计数器值一起发送到接收节点。接收节点在接收到加密数据后，用自己的该连接计数器确认接收到的计数器值。在确认之后，接收链路使用基于状态的流密码，共享密钥和加密状态解密加密数据。两个节点是状态同步的，使得每个节点在使用基于状态的流密码和相同密钥时产生相同的密码流。在同步丢失的情况下，可以使用涉及在两个节点之间的4次握手处理并涉及随机交换（也称为标记）的可能的重新同步过程。

摘要： Pretreatment method and apparatus to remove matrix ions from a liquid sample, prior to separation of the sample analytes (e.g. by chromatography), by flowing the liquid sample into a sample compartment (16) and stopping the flow. The sample compartment has a wall comprising an ion exchange membrane (12, 14) having exchangeable ions of the same charge as the matrix ions to be removed. A regenerant liquid stream (22, 24) flows through a regenerant flow compartment (18, 20) on the other side of the membrane from said parked liquid sample. Matrix ions in the parked liquid sample are transported across the membrane into the regenerant flow compartment (18, 20). Suppression may be performed electrolytically and/or chemically. A concentrator column may also be used.
